WebSolution : Angle to the mirror surface=40 0. Therefore, angle of incidence= 90 0 -40 0 =50 0. According to the second law of reflection, angle of incidence is equal to the angle of reflection. Therefore, angle of reflection=50 0. Question 4: A ray of light is incident normally on a plane mirror.
