It is a simple device to determine the ultrasonic velocity in liquids the principle is based on accurate measurement of wave length in the medium Ultrasonic wave s of known frequency are produced by a quartz plate fixed at the bottom of the cell. The waves are reflected by a movalbe metallic plate. If the separation between these plates is exactly whole multiple of sound wavelength, standing waves are formed. The acoustic resonance gives rise to electrical reaction on the generator and anode current becomes maximum. From the knowledge of wavelength, velocity can be obtained.
To determine velocity of ultrasonic waves in a liquid, complete apparatus consists of high frequency R.F. Oscillator 3-8 MHz, Crystal with tank, long tube Spectrometer with 7 "protracted circle, sodium lamp with wooden box and transformer
