Answer Details
Dispersion of light by a glass prism is due to the different speeds of the various colors in glass. When light passes through a prism, it bends or refracts, and each color bends differently because they have different wavelengths and travel at different speeds in the glass. This causes the colors to spread out or disperse, creating the beautiful rainbow of colors that we see. The amount of refraction depends on the angle at which the light enters the prism and the refractive index of the glass. The high density of the glass also plays a role in this process by slowing down the speed of light.
