If the angle of incidence of a light source to a shiny surface is 30 degrees, what will the angle of reflection be?
150 degrees
90 degrees
60 degrees
30 degrees

Angle of incidence always equals angle of reflection. Think of a tennis ball being hit into a wall. The ball will bounce off at the same angle that it approached with. The angles mentioned are formed through the line called the "normal", which is the line perpendicular to the surface.
