Schlieren photography has been used many years in physics; however it has proved to be exceptionally valuable in the study of ultrasonic waves in liquids. Part of the reason for its value is that many of the ultrasonic phenomena studied have their optical analogies. Thus, when one studies ultrasonic images the actually is studying a general wave phenomena from a perspective that is impossible with light alone. Examples are given of ultrasonic schlieren photographs as are conclusions possible from their study.
