9.5 Doppler effect

Experiments

Here are experiments our science specialists have selected to support the IB* topic.

Doppler Effect

Experiment #5 from Advanced Physics with Vernier — Beyond Mechanics

In this experiment, you will

  • Use video analysis of the waves produced by a stationary source to determine the frequency, wavelength, and velocity of the waves in water.
  • Perform similar analysis to determine the effect of a moving source on these quantities
  • Determine the shifted frequency an observer would detect as the source approaches or recedes.
  • Derive an expression relating the shifted frequency to the speed of the object and of the wave in the medium.
