Optical diffraction study of ultrasonic sound velocity in nitrous oxide and ammonia gases

Creator:

Strauch, Joseph George

Abstract:

The velocity of sound in gases was measured, using an ultrasonic wave train as a diffraction grating. The fundamental problems involved in the optical technique are discussed. An apparatus utilizing an objective lens of focal length 1.5 m and aperture f/20 was constructed and used at an ultrasonic frequency close...
