Reflection occurs when light traveling through one material bounces off a different material. The reflected light still travels in a straight line, only in a different direction. The light is reflected at the same angle that it hits the surface. The angle of incidence is equal to the angle of reflection. The angle of incidence is the angle between the incoming light and a line perpendicular to the surface called the normal. The angle of reflection is the angle between the reflected light and the normal. The symbol Ɵ means “angle'' and arrows represent rays of light.
