The change in direction of a ray depends on the change in the speed of the light and can be used to calculate the refractive index. For the example above the refractive index \(n\) of the glass is ...
Light changes speed as it passes from one medium to another. This is called refraction. The frequency of light does not change as it refracts. The refractive index of a material is a measure of ...
