The 1st and 2nd Commandments

The 1st and 2nd Commandment-

1. I am the Lord thy God; thou shalt not have strange gods before Me.
2. Thou shalt not take the name of the Lord thy God in vain.

Compare And Contrast about the 1st and 2nd Commandment-

Its says much more about the commandments but in the if commandment its means that the lord thy god and that they shalt not have strange gods before me. but it means so much to god because he wants us to say it in proud and honor. the second commamndment means that they shalt not take the name of the lord thy god in vain. like i had said God wants us to say it in proud and honor in different ways to honor his word to him.

Interactions Of Light Waves

Refraction Meaning-
The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different density. The ability of the eye to bend light so that an image is focused on the retina.

Prism Meaning-
an object that has this shape. A prism of glass or a similar transparent material can be used to bend different wavelengths of light by different amounts through refraction. This bending separates a beam of white light into a spectrum of colored light.

These are pictures about how Interaction waves work.

The Law Of Reflection

When a ray of light strikes a plane mirror, the light ray reflects off the mirror. Reflection involves a change in direction of the light ray. The convention used to express the direction of a light ray is to indicate the angle which the light ray makes with a normal line drawn to the surface of the mirror. The angle of incidence is the angle between this normal line and the incident ray; the angle of reflection is the angle between this normal line and the reflected ray. According to the law of reflection, the angle of incidence equals the angle of reflection. These concepts are illustrated in the animation below.

Law Of Reflection

Light is known to behave in a very predictable manner. If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The diagram below illustrates the law of

reflection.

In the diagram, the ray of light approaching the mirror is known as the incident ray(labeled I in the diagram). The ray of light that leaves the mirror is known as there flected ray (labeled R in the diagram). At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. This line is known as a normal line (labeled N in the diagram). The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection. (These two angles are labeled with the Greek letter "theta" accompanied by a subscript; read as "theta-i" for angle of incidence and "theta-r" for angle of reflection.) The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

Remember the Sabbath day, to keep it holy.
Honor your father and your mother.
You shall not murder.
You shall not commit adultery.
You shall not steal.
You shall not bear false witness against your neighbor.

You shall not covet.

*Why The Ten Commandments Are Called The Decalogue?

obviously come from the Hebrew Bible, but it is not so obvious to determine exactly what they are or how to count them. These commandments are recorded in two different biblical chapters Exodus 20:1-17 & Deuteronomy 5:6-21, yet each text is slightly different, and neither passage explicitly numbers the commandments one through ten.

* How The Ten Commandments Guide And Norsish The Spirital Well-being Of A Christian Believes?

The Ten Commandments are an excellent piece of literature of the Old Testament, which was given by God Himself, through Moses, to the people of Israel, and which was destined to shape the morals of the society of the world.

The Ten Commandments, also known as the Decalogue, constitute the ethical code by which the human race is guided, on the one hand, to believe in the true God, and, on the other hand to sustain the godly society in the attainment and application of God's will on earth. The Ten Commandments were kept undefiled and handed down to us as a treasure and monument of Christian civilization. The Christian Church has embodied the Ten Commandments as a basic moral code of, discipline toward God and toward men. "There is probably no human document which has exercised a greater influence upon, religion and morals than the Ten Commandments."

Moses is an outstanding personality of the Old Testament; he is known not only for his leadership and statesmanship, but especially as a religious forerunner of Judaism. His destiny was planned by God Himself to lead the people of Israel out of the Egyptian bondage and into the wilderness, a land north of Mt. Sinai and between Egypt and Palestine, their new dwelling place. Moses knew this land well because he had spent 40 years in exile from the Egyptians in this area with a great man, his father-in-law Jethro, who gave counsel to him.

         

Electromagnetic Waves

*How Electromagnetic waves are differ from each other?

When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves.

Radio waves, television waves, and microwaves are all types of electromagnetic waves. They differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.


Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom.



* Some uses for Radio Waves and Micorwaves?


Radio waves are the lowest-energy, lowest-frequency and longest-wavelength electromagnetic waves. They are produced when an alternating current flows in an aerial and they spread out and travel through the atmosphere. They are not strongly absorbed by the atmosphere. Another aerial is used as a detector and the waves produce an alternating current in it, with a frequency that matches that of the radio waves. Anyone with a receiver can tune it to this frequency to pick up the radio waves so they are suitable for broadcasting (for example, radio and TV programmes) to large numbers of people. An advantage is that this method of communicating does not require wires to transmit information. A disadvantage is that radio stations using similar transmission frequencies sometimes interfere.
A common mistake is to think that we can hear radio waves. We cannot hear any electromagnetic radiation. The radiation is used to carry a signal that is converted into a sound wave by the receiver.
Medium wavelength radio waves are reflected from the ionosphere, a layer of charged particles in the upper atmosphere, so they can be used for long distance communication.

* Examples of how infared waves and visible light are important in our life?

Infrared (IR) is a form of electromagnetic radiation that has a wavelength slightly longer than the color red in the visible light spectrum. Infrared radiation is created when objects are heated at temperatures not quite high enough to make them glow. You can detect infrared radiation by the heating effect it has on your skin. Special sensors are also used to detect IR. This type of radiation is used in electric heaters, greenhouses and night vision sensors

Properties Of Sounds

Sound has a huge impact on our day to day lives. Just think of how much of our technology involves sending or receiving sounds in various forms.

Most people don’t fully understand what sound is.

In this section we will be looking at the basic properties of sound.

Sound is a longitudinal wave.

Remember that longitudinal waves are made up of areas where the wave is compressed together, and other areas where it is expanded.

This would agree with the way that humans themselves make sounds. We force air, sometimes harder, sometimes softer, through our vocal cords.

In the process the air is either squished or allowed to move freely… making the air into a longitudinal wave!

We will look in detail at three fundamental characteristics of sound: speed,frequency, and loudness.

Speed

The speed of sound in air actually depends on the temperature of the air.

As a standard, we will say that the speed of sound is 340m/s at 15°C. If you are not told anything different in a question, use this value.

If you did need to calculate the speed of sound at a different temperature, you could use this formula as a rough estimate (you are not required to memorize this formula)…

v = 331.5m/s + 0.6T

v = velocity of sound (m/s)

T = temperature

These are the properties of sounds that it explains so much of it and how it gives more information about sound waves!

How The Church Is Human And Divine

How The Church Is Human And Divine:

The Church always walks the same path as her divine Founder. Like Him she encounters those who accuse her of contradictory crimes and vices. They find her too worldly, and at the same time out of touch with “the real world.” They insist that she stay out of politics and condemn her for supposed silence on issues. In short, the world demands that the Church be human and then complains that she is not divine. Thus in a roundabout way the Church’s critics reveal the paradox of the Church: like our Lord, she is both human and divine.

That the Church is human is all too apparent. Of course, when most people talk about the Church being “human” they are referring to her failures (as if that is all it means to be human). But the human dimension of the Church continues in heaven, where there will be no failures. That the Church is human means primarily that she is built out of the living stones of individual human persons. She exists in the world in a human manner and through human means. She continues the presence of Christ by human words, actions and relationships.

Unfortunately, since our human nature is fallen and wounded, the Church’s human dimension also appears in weakness. This often scandalizes because we hope to find purity and strength in the Church but instead encounter quite the opposite. And yet, as much as we ought to find holiness in the Church, it is in another sense not surprising that we encounter weakness. The crowds in Jerusalem encountered human weakness in our Lord. Not, to be sure, moral weakness. But weakness nonetheless – the weakness of a man betrayed, beaten, scourged, and crucified. The crowds looked and, seeing the man of sorrows, in effect asked, “That? Is that God?” The Church always walks the path of her Founder. So people look upon the Body of Christ and, finding her laboring under human weakness, they ask, “That? Is that the Church of God?” Indeed she is – appearing in human nature and laboring under human weakness, as did her Lord. And just as our reaction to the suffering Lord should be one of pity and not outrage, so also we should respond to His Body, the Church suffering from the scandals of her members.

Our outrage at scandals and weakness in the Church comes from the fact that the Church is more than merely human – and we sense that to be true. She is, as we confess every Sunday, holy. This dimension of the Church is not as clear to us, just as Jesus’ divinity was veiled by His humanity. We call the Church “holy” because she bears God’s own life and grace. She teaches divine truths and administers the Sacraments of salvation. Her very soul is the Spirit of God.

In a sense, it should not surprise us that the Church suffers and always has suffered scandals. Not only because our Lord promised that it would happen but also because any human institution suffers them. What should surprise us is that the Church has survived her scandals. No other human institution could survive the scandals that the Church has seen. That she can survive them hints at the fact that she is more than merely human. Her weakness that endures testifies to something more than human at work within her. She is human, yes, with all the weakness that comes with that. But at once she is also divine, the Body of Christ.

Comfort with this paradox makes a heart truly Catholic. It enables one to trust in the Church as Christ’s voice and presence in the world – the very oracle of God, as Newman said. It likewise enables him to see scandals in the Church for what they are. He can see the horror of a scandal, and yet not stop trusting the Church. He knows the Church is at once divine…but also in need of reform. A person with such faith is not undone by scandals, because he knows the Church consists of weak human members (like himself). He knows that the Church is a pilgrim, en route to heaven, and always becoming more perfectly what she is.
