In physics, reflection is the rebounding of light or other kinds of waves (such as sound)
from a surface. Most objects are visible because of the light that reflects
Smooth surfaces such as clean glass, reflect
light back to the observer in parallel rays, which is called regular
reflection. Surfaces that are not smooth reflect light to the
observer in many different directions, which is called diffuse

- In mathematics, reflection is a way of transforming
a shape in the same way that a mirror does. The reflection of a shape in a mirror line is an identical shape
that has been flipped over. When an object is placed a certain distance
in front of a mirror, its image in the mirror appears the same distance
away from edge of the mirror. Likewise, all the points on a shape and
all the points on its image are same distance away from the mirror line.
