Notice that they mix the refractive indices over the whole frequency range to compute the value of $\alpha$. impressionism art for kidsWebGlass has a slightly different refractive index for different colours. For red light, the refractive index of glass is around 1, whereas for blue light, the refractive index is around 1. According to Snell's Law, the different refractive indices would cause the different colours of light to bend different amounts. impressionism art for sale

"WebOptical Density and Light Speed. Refraction is the bending of the path of a light wave as it passes from one material to another material. The refraction occurs at the boundary and is caused by a change in the speed of the light wave upon crossing the boundary.
