The document discusses the law of reflection which states that the angle of incidence is equal to the angle of reflection, with the incident ray, normal line, and reflected ray all lying in the same plane. It also describes how mirrors cause left-right reversal of images and how multiple mirrors can produce multiple images, with the number of images determined by a formula involving the angle between mirrors. Both specular/regular and diffuse/irregular reflection are defined based on smooth vs rough reflective surfaces.
7. MIRROR LEFT-RIGHT
REVERSAL
The left side of the object
appears as the right side of the
image and the right side
appears as the left. This effect is
known as the mirror left-right
reversal.
