As light rays reflect off of mirrors and pass through lenses, they create images of the object emitting or reflecting
the light. In plane mirrors, the images are reversed left to right, though they remain upright. In curved mirrors and
lenses, the interactions between objects and their images are more complex. Convex and concave mirrors and lenses
can cause images to be diminished or enlarged, upright or inverted, and real or virtual.
