Question

What are the rules based on bending of light ?

Answer 1

first of all the bending of light is caused due to change in velocity of light when jt travels from one medium to another...



when a ray of light passes from a rarer medium to a denser medium, the ray of light bends towards the normal...this is bcz the velocity of light decrease as the rays go from rarer to denser medium..

when a ray of light passes from a denser medium to a rarer medium,the ray of light bends away from the normal ....this is bcz the velocity of light increases as the rays go from denser to rarer medium.



hope it will help uu

Answer 2

So you asked what are the rules based on bending of light?

Bending of light means nothing but refraction.

Ever wondered why does light bend?

Well I have got the answer to it.

Its because of the change in speed of two media

So wait , then it does also mean that if there is no change in speed in two media then the light will pass straight.

Well if light travels from rarer to denser medium it will bend towards the normal

Else(i.e. from denser to rarer) light will bends away the normal .

Hope this helps you!!!
