Want this question answered?
Waves may bend if they move from one medium to another.
change of medium causes light to bend
The speed of the wave in the different mediums.
The change in speed causes the light to bend. If it is travelling from an optically dencer to an optically rarer medium the ray will bend away from the normal. But if it is travelling from an optically rarer to an optically denser medium then it will bend towards the normal.
Light bends because of the difference of speed in each medium.

It must pass though a medium from an another medium.

Light rays bend when they enter a new medium at an angle because they either slow down or speed up. They speed up the most if they are in a vacuum.

Everybody knows change in speed of light causes to bend light. But why does light bends towards normal when passing from rarer to denser and vice versa?
