Question

A ray of light is reflected by an angle of 15◦
from a smooth polished surface.
By how much will the angle of reflection reduce if the angle of incidence is divided by 3?

Answer 1

Answer:

the reflected angle is reduced by 10

the angle I is divided by 3 (give)

so, angle i = 15/3=5

by laws of reflection always angle i = angle r

so firstly angle r=15

if angle I reuced then also angle r reduce so

angle r reduces by 10
