The light beam is reflected from the mirror surface at an angle of 28 °. Determine the angle between the incident and reflected rays.
The angle of incidence of the ray a on the mirror surface is equal to the angle of reflection b (in the plane passing through the rays and normal to the surface at the point of incidence): a = b.
The angle c between the incident and reflected rays will be equal to twice the angle of reflection:
c = b + a = 2b = 2 * 28 deg. = 56 deg.
Answer: 56 degrees.
