When a light beam passes from an optically denser medium to an optically less dense medium(and vice versa),the direction and the speed of light changes.
My question is why light must bend when it goes from one medium to another.
Say,it goes from air to water. Water is optically denser than air, which means the speed of light in air is higher than the speed of light in water.Why doesn't the light just slow down in water, why does it have to bend in the process?
