OBSERVATION OF STATIONARY WAVES

(A them EB .

Submitted by: Shukichi Yanlana, Kyoto Gakugei University, Fushimi-ku, Kyoto, Japan. Checked by: Neal T. Haygood, Wakefield High School, Arlington, Va. PREPARATION

The stationary wave is a fundanlental concept in quantum chemistry which is based 011 the Schrodinger wavc equation. A convenient method of observing stationary waves is presented here. Three nails are driven into a 10 X 2 X '/,-in. hoard at three corners and a rubber band is stretched around the nails. DEMONSTRATION

The assembly is arranged vertically in front of a bright TV screen, perpendicular to the scanning lens. If one of the long segments of the band is put into oscillation by plucking, the shape of its stationary wave may be seen. If no wave can be found adjust the relative tensions of the rubber hand segments.
