L4-01. Optical Board - Rectangular Slab
To demonstrate refraction and to show displacement of rays by a uniform slab of glass.
Optical board with slit baffle, concave and convex lenses, and rectangular slab on mount.
A slit baffle with concave and convex mirrors are used to produce a beam of parallel rays of light. A rectangular slab of lucite placed at an angle in the rays of light produces refraction at each surface, leading to displacement of the light rays. The central ray in the picture is reflected internally off the end surface of the slab and directed upward.
