An ultrasonic interferometer has been developed using an air-liquid surface as a reflector. Because of certain simplifications that occur, it is found advisable to recast the mathematical interpretation of the results along different lines than previously. The effect of a loaded piezoelectric crystal at resonance is taken as a variable resistance, and the measured values of this resistance are interpreted to calculate absorption in the liquid.
