Determination of Ultrasonic Velocity in Liquid – Acoustical Grating Method

Determination of Ultrasonic Velocity in Liquid (Acoustical Grating Method) Determination of Ultrasonic Velocity in Liquid – Acoustical Grating Method. Acoustical Grating Method Principle: When ultrasonic waves travel through a transparent liquid, due to alternate compression and rare action, longitudinal stationery waves are produced. If monochromatic light is passed through the liquid perpendicular to these waves, […]
