The measure of how much a ray of light bends when it enters the material is called the index of refraction.
This is called refraction.
refracted light
Light does not bend as it passes through a material. It bends when it passes from one material to another. This is called refraction. Light can also be dispersed, that is separated into its different colours, if it is refracted enough.
sometimes bends towards the normal
