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.
Does destructive interference violate the principle of conservation of energy? Briefly explain.
Maximum power transfer: Every source of EMF has internal resistance. If it is required to develop the maximum possible amount of power in an external load, then the load resis
