Abstract
By using Michelson's interferometer, the wave-form of a sound produced by a condensed spark has been studied. It has been found that the wave consists of a high frequency oscillation of air of the order sec., having two discontinuities, one being due to a condensation at the head and the other to a rarefaction at the tail. The variation of the wave-form has also been observed, as it propagates onwards.
