L2-01. Optical Board - Plane Mirror
Purpose
To demonstrate reflection from a plane mirror.
Equipment
Optical board with plane mirror.
Suggestions
Adjacent concave and convex lenses are used to produce a parallel beam of light rays.

Description
This demonstration shows that the angle of incidence is equal to the angle of reflection. Use colored slits to show that this is good for all colors. (There is no chromatic aberration in a reflecting telescope.)
