Question

if the Ray of light is incident on a polished surface making angle with surface is 30 the angle of reflection will be
A=60
B=90
C=0
D=30​

Answer 1

Answer:

angle of incidence equal to angle of reflection

so,

angle i = angle r

30° = 30°

angle of reflection from surface will be 30°

Explanation:

option D is correct

Answer 2

A=60

Explanation:

with the surface 30,So

angle with the normal =90-30=60

angle of incidence=60

according to the laws of reflection,

angle of incidence angle of refraction.

therefore

angle of refraction =60
