Cavitation is formation of vapor bubbles of a following liquid in a region where the pressure of liquid falls below its vapor pressure. Cavitation is usually of
Ultrasonic waves can be detected by various methods as listed below: (a)Using radiometer: Ultrasonic waves can be detected using Radiometer. In this method ultrasonic beam
A magnetostriction generator can produce ultrasonic waves of comparatively low frequency. For generating high frequency ultrasonic waves, piezoelectric generator is used. Piezoelectric Generator.
Magnetostriction: When magnetic field is applied across the length of a ferromagnetic rod such as Nickel, then change in the length of rod is observed.
Ultrasonics can be produced by means of (i) Galton’s Whistle (ii) Magnetostriction Generator (ii) Piezoelectric Generator or Oscillator. Galton’s Whistle. It contains of essentially a short
The following are the main properties of ultrasonic waves: The ultrasonic waves cannot travel through vacuum. These waves travel with speed of sound in a
Definition of ultrasonic waves: Ultrasonic waves are acoustic waves whose frequency is more than 20kHz .They travel with the speed of sound. Hence their wave
