REFRACTION OF LIGHT
°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°

Refraction is a change in the direction of wave propagation due to changes in its transmission medium.

Refraction is the inclination of light (it also occurs with sound, water and other waves) because it comes out of a transparent material that can pass without light scattering. Objects are clearly visible when a transparent material such as a smooth window is seen through glass or water matter in another

This tendency by refraction makes it possible for us to make lenses, eyeglasses, magnets and rainbow magnifiers. Even our eyes depend on the inclination of light, without refraction, we will not be able to concentrate on light our retina...
