Question
The law of reflection states that the angle of incidence
is equal to the angle of reflection. What is the angle of incidence when the angle of reflection is 30°? ÂSolution
According to the law of reflection, the angle of incidence is always equal to the angle of reflection.  So, if the angle of reflection is 30°, the angle of incidence is also 30°.  This holds true for all types of reflections, whether on a flat mirror or a curved surface.
