Question

what is refraction why does a Ray of light bend on refraction​

Answer 1

When a tay of light travel from one transparent medium to another transparent medium in oblique direction it bend away from its path . this bending is called refraction. a light bend on refraction due to refraction property and also because it passes from one medium to medium !

Answer 2

Answer:

the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.When a light ray travelling in a medium

encounters a boundary leading into a second

medium, part of the incident ray is thrown

back into the original medium.

Explanation:

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. ... When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line
