Ultrasonic Grating Apparatus

Description

Use the Ultrasonic Grating Apparatus to demonstrate the interaction of longitudinal sound waves and transverse light waves or precisely determine the speed of sound in liquids. Use with any clear non-aggressive liquid of low electrical conductivity.

  • The Ultrasonic Grating Apparatus is both a unique demonstration of the interaction of longitudinal sound waves and transverse light waves and also a method for the precise determination of the speed of sound in liquids, which is otherwise difficult to do in the undergraduate lab.
  • The core of the apparatus is a parallel-sided glass tank that houses the liquid sample and contains a lead zirconate titanate (PZT) ultrasonic transducer.
  • The transducer is energized by an RF signal in the 8 to 12 MHz range.
  • Resonances can be found to set up a standing wave field in the liquid, which results in a periodic variation of the liquid's refractive index along the tank.
