rules of reflection
angle of incidence must equal angle of reflection
normal ray, angle incidence and reflected ray
must be the same size and shape
concave mirror
a light ray parallel to the principal axis is reflected to focus
a light ray through the center of curvature is reflected onto its self
a ray through the focus will reflect parallel through the principal
