Barbershop mirrors:Parallel mirrors with light bulb.

Barbershop mirrors: Parallel mirrors with light bulb. This apparatus demonstrates multiple reflections between parallel or slightly angled mirrors. There are two mirrors on adjustable bases facing each other. A light source is mounted about halfway between the mirrors. One mirror is mounted higher than the other so that one can see the multiple reflections more easily. Angling one mirror slightly to the other causes the reflections to veer off left or right in an arc of smaller images. (A great example of multiple reflections is the Hall of Mirrors in Versailles, France. Since the observer is between the mirrors, the effect is impressive.)
