Wave Machine Model Feb 20, 2011
The Wave Machine model was published as a supplemental simulation for the article "Standing Waves in a Nonuniform Medium" by Paul Gluck in The Physics Teacher 49(2), 76-77 (2011). The model simulates the wave machine produced by John Shive at Bell Laboratories and made famous by the PSSC Simple Waves film. The machine consists of horizontal bars welded to a torsion rod that is perpendicular to the bars. The simulation allows the user to change the lengths of the bars, thereby simulating the effect of a wave propagating in a non-uniform medium. |
