Stationary ultrasonic waves, determination of wavelength
Principle: An ultrasonic wave is subjected to hard surface reflection from a metal plate. The reflected wave superimposes on the incident wave, coincident in phase and amplitude, to form a standing wave. The intensity of this wave along the direction of propagation is measured using a movable ultrasonic receiver.
Tasks:
1. Determine the intensity of a standing ultrasonic wave by moving an ultrasonic receiver along the direction of propagation.
2. Plot a graph of the measured values against the distance.
3. Determine the wavelength of the ultrasonic wave.
