Image Formation in Plane Mirrors Visit The Physics Classroom's
Flickr Galleries and enjoy a photo overview of the topic of
reflection and mirrors. Other Multiple Mirror Systems Besides
right angle mirror systems, there is a wealth of other multiple
mirror systems that involve two or more mirrors. If two plane
mirrors are placed together on one of their edges so as to form
a right angle mirror system and then the angle between them is
decreased, some interesting observations can be made. One
observes that as the angle between the mirrors decreases, the
number of images that can be seen increases. In fact as the
angle between the mirrors approaches 0 degrees (i.e., the
mirrors are parallel to each other), the number of images
approaches infinity. The generation of two images is not
difficult to explain; each of the two mirrors produces an image
due to the single reflection of light off one of the mirror
faces to an observer's eye. The remaining images are produced as
the result of multiple reflections of light
