Originally Answered: If the angle between the mirror and the incident ray is 30 degrees, what is the angle of reflection? The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) makes a right angle. So, the angle of incidence is 90 - 30 = 60 degrees.
