Laser Diode for the Debye-Sears Effect

The Laser Diodes are for use in demonstrations of the Debye-Sears Effect and connect to the test vessel. Supplied with a 1 metre lead and barrel connector for connecting to the Ultrasonic CW Generator. All lasers have been measured to determine their wavelength specifically and the results are logged.

THE DEBYE-SEARS EFFECT

In 1932, Debye and Sears for the first time demonstrated the refraction of light as it passed through a liquid being subjected to high-frequency vibrations. In this process, the density maxima and minima of a stationary ultrasonic wave act like the elements of an optical diffraction grating. The grating constant here is equal to half the wavelength and therefore dependent on the frequency and speed of the ultrasonic waves transmitted through the medium (e.g. water, glycerin, oil).
