6D10.35ripple tank incoherenceAJP 56(8),745The necessary conditions for interference are shown with a dripping water double source that can be adjusted to show irregular changes in initial phase differences.
6D10.36coherence and interferenceAJP 40(3),470An interference pattern results from a laser grazing the wall of a glass tube. The effect is not observable with non coherent light.
