Light Diffraction by Ultrasonic Waves
Abstract
In this paper, diffraction of light by ultrasonic
waves is examined. The equation for the wavelength
of sound in water is derived and the Raman and Nath equations for the intensity distribution due to 1)
pure progressive waves 2) pure standing waves and
3) waves of various standing wave ratios are presented.
The paper is divided into three sections. The
first part deals with the background and theory and
is intended as an orientation for the reader. The
second part of the paper discusses the apparatus used
in performing the experiments and the final portion
deals with the experimental procedure and the results
of the work.
