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