Question

if a ray hits a plane mirror at an angle of incidence of 35 degrees, what is the angle between the incident and reflected rays?

Answer 1

Answer:

Angle of incidence and angle of reflection are the angles that incident ray and reflected ray, makes with the normal (to the mirror), respectively. In this case, the angle of incidence is given as 35 degrees, thus the angle of reflection is also 35 degrees.

Explanation:

Answer 2

Answer:

Thus, the angle between the incident and the reflected rays is the sum of angle of incidence and angle of reflection, that is, 70 degrees (= 35 + 35 degrees)
