Question

Solve the following numerical. Find the angle of reflection in the following.

2 points



(a) 30 degrees

(b) 45 degrees

(c) 60 degrees

(d) 90 degrees​

Answer 1

Answer:

Correct option is

C

60

According to first law of reflection incident and reflected angles are equal. So, reflected angle will be 30 degrees. Reflected angle and angle B together make up the angle between normal and the surface that is 90 degrees. So, Angle b = (90 - reflected angle), which is (90-30) = 60 degree.
