What are the methods for producing Ultrasonic waves?
Ultrasonic Production:
Three methods there for producing Ultrasonic waves are as given below:
a. Mechanical generator or Galton’s whistle.
b. Magnetostriction generator.
c. Piezo-electric generator.
In this section, know the method of producing ultrasonic waves by using Magnetostriction method.
Explain irreversible process A process which takes the system to the non equilibrium state is known as irreversible process. *It can't be retraced in the reverse direction.
Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential in the hollow conducting shell is found to be:
