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.
