A light ray leaves point A in Figure 1, reflects from the mirror, and reaches point B. How far below the top edge does the ray strike the mirror? What if the distance from point B to the mirror was reduced by 5 cm?

♦ Relevant knowledge
Mirrors are the objects that is designed to reflect light that hits it. Its law states it that the angle from which light hits the mirror (also known as angle of incident is equal to that of the reflection angle).
