Original Summary:
"Explains that the superposition of single pulses from two sources leads up to the interference pattern formed by two periodic waves. Shows the effect on an interference pattern produced by two point sources of changing the wave length, separation of the sources, or the phase of the waves. Explains diffraction as a form of interference. Shows waves diffracted around obstacles and through slits to illustrate the effect on the pattern of varying wave length, obstacle size, and slit width. Demonstrates multiple slit diffraction" - Summary from Worldcat.
