Acoustic Doppler effect with universal counter

Продукт No: P2150405

Principle

If an emitter of sound or a detector is set into motion relative to the medium of propagation, the frequency of the waves that are emitted or detected is shifted due to the Doppler effect.

Benefits

  • Easy frequency setting thanks to digital function generator
  • Intuitive measuring instrument
  • Results well reproducible because of the motor-driven car

Tasks

  1. Measure the Doppler shift for varying frequencies and velocities for a moving sound emitter. Compare the measurements with the values predicted by theory and validate equation (4).
  2. Measure the Doppler shift for varying frequencies and velocities for a moving detector. Compare the measurements with the values predicted by theory and validate equation (6).

What you can learn about

  • Wave propagation
  • Doppler shift of frequency
