It might bend if it transfers from one medium to another, or when it hits another object. Hope this helps.
The bending of a wave occurs when the wave hits a object?
Yes,It bends when traveling from 1 media to another.
It must pass though a medium from an another medium.
Waves may bend if they move from one medium to another.
The velocity of the light wave differs in different media. This is the main cause for bending of light ray as it traversed from one medium to the other
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?
Light bends because of the difference of speed in each medium.
diffraction
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.
