Determination of Sound Velocities in Liquids Using Light Diffraction of Ultrasonic Waves
Abstract
Previous to the writing of this paper,
Paul A. McIntosh, a 1964 Kalamazoo College graduate, examined diffraction of light by ultrasonic waves. More specifically, he derived the
equation for the wave1ength of sound in water
and presented the Raman and Nath equations for
the intensity distribution due to pure progressive
waves, pure standing waves, and waves of various
wave ratios.
My continued work in this area involved
working out a method of determining sound velocities in small quantities of transparent liquids;
deionized water, steamdistilled-wood turpentine,
methyl alcohol, and mineral oil. In addition, the
wavelength of a continuous gas laser light was
calculated.
