Answer 1

the phenomenon of bouncing back of light into the same transparent medium after hitting an opaque surface is known as reflection of light

Question 2

Answer 2

1. angle of incidence is equal to angle of reflection
2. the incident ray, reflected ray and the normal at the point incidence, all three lie in same plane

Question 3

what is g (angle of glancing)- same diagram as from laws of reflection

Answer 3
