An Ultrasonic Interferometer is a simple and direct device to determine the ultrasonic velocity in. liquids with a high degree of accuracy. The principle used in the measurement of velocity (V) is based on. the accurate determination of the wavelength (λ) in the medium. If the separation between these two plates.

Melde's Vibrating String experiment is an elegant way to introduce students to the concept of standing waves. The apparatus consists of a string and an oscillator to generate different frequencies. Melde's experiment is ideal to study the behavior of standing waves.
