Abstract
ULTRASONIC velocities in liquids determined by various methods have been reported in the literature. The interferometer method1, though widely adopted by a number of workers, permits velocity measurements only at low ultrasonic frequencies. The Debye–Sears's diffraction method2 and the Hiedemann method3 of visibility are applicable only for the study of transparent liquids. Elaborate technique is required for velocity determinations by the pulse method4.
