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.
What does it signify to say that the electric potential is a function of x only? More exclusively what does the equipotential diagram (in 3-dimensional space) look like in the case
