Question

what is refraction of light......?????​

Answer 1

Answer:

$\huge\boxed{ \fcolorbox{blue}{red}{answer}} \:$

the bending of light when it passes from one medium to another is called refraction of light.

the change in direction of light when it passes from one medium to another, is called refraction of light.

the refraction of light takes place on going from one medium to another because a speed of light is different in two media.

optical medium is a medium in which the speed of light is more. Air is an optically rarer medium as compared to glass and water.
