Ultrasonic Grating Physics Lab Experimental Device

This experimental system is designed to study ultrasonic light diffraction, also known as the acousto-optic effect. When light propagates through a liquid medium carrying ultrasonic waves, periodic variations in the medium's refractive index act as an optical grating, causing the light to diffract.

By performing the experiment, users can observe the interaction between light and sound waves, understand the principles of acousto-optic modulation, and measure the propagation speed of sound in a liquid medium. The system also provides practical insight into the applications of acousto-optic technology in modern optical and measurement systems.
