alleryStart learning →A light ray hits a plane mirror and makes an angle of 30 degrees with the mirror surface. What is the angle of reflection?
A30 degrees
B90 degrees
C120 degrees
D60 degrees
Answer & Solution
Correct answer: D. 60 degrees
The angle with the normal is 90 - 30 = 60 degrees, and the angle of reflection equals the angle of incidence measured from the normal.
