Question

The angle between the plane
mirror and incident ray is 42
What is the angle of incidence
and angle of reflection?
?​

Answer 1

Answer:

The angle between the reflected ray and the surface of the mirror is 48 degrees. So, the angle of reflection + this angle (48) will make a right angle. Thus, the angle of reflection = 90 - 48 = 42 degrees. As the angle of incidence and the angle of reflection are equal, both angles equal 42 degrees.
