Students experiment to find that as the angle between two mirrors is increased or decreased, the number of reflected images increases or decreases. A relationship also exists between the size of the angles and the number of edges of the mirrors that are visible. Placement of the images in the mirrors depends on the distance from the surfaces of the two mirrors.
