摘要:
An undergraduate experiment is described in which Schlieren photographs are made of the sound waves produced by an electric spark. Electronic control of the time lapse between initiation of the sound pulse and the xenon flash tube illumination allows observation of the wavefronts at various stages of their progress through air or of their reflection from curved surfaces. A method of determining the velocity of sound in air is described.
