change of medium causes light to bend
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
refraction

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?

refraction
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.

because when light hits a different martial it slows and change it direction like ridingbike from the road on to the sand.

false
If the light from a distance galaxy passes near a massive cosmic object, then the gravity of that object will distort space-time. That will cause the light to bend.

Gravity. (Or the shape of space - which is molded by gravity.)
