Question

what is meant by refraction and reflection of light​

Answer 1

Explanation:

Refraction is the bending of light as it passes from one substance to another. Here, the light ray passes from air to glass and back to air. The bending is caused by the differences in density between the two substances.

Answer 2

Explanation:

reflection of light. ..

the phenomena of change in path of light in same phase with an angle.. I. e.. incident rays fall on the plane surface.. and reflect by an angle which is equal to angle of incident

I. e.. phase of incident light doesn't change

refraction of light

it is the phenomenon of change in path of light when the incident ray pass through one medium to another medium...

I. e. here change in phase occurs
