Acoustic Doppler effect with universal counter
Article No: P2150405
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 Measure the Doppler shift for varying frequencies and velocities for a moving sound emitter. Compare the measurements with the values predicted by theory. Measure the Doppler shift for varying frequencies and velocities for a moving detector. Compare the measurements with the values predicted by theory. Learning objectives Wave propagation Doppler shift of frequency
