To measure the Ultrasonic Velocity in Liquids.The principle used in the measurement of velocity (ν) is based on the accurate determination of the wavelength (λ) in the medium. Ultrasonic waves of known frequency (f) are produced by a quartz crystal fixed at the bottom of the cell. These waves are reflected by a movable metallic plate kept parallel ..

In this technique the specimen is cemented to a quartz rod of identical cross section and resonant frequency of the composite system (fc) is determined using the apparatus. The resonant frequency of the quartz crystal (fq) is also determined. From the knowledge of fq, fc and the masses of the quartz and the specimen, the resonant frequency of the s..
