To demonstrate the Doppler effect.


Self-contained Doppler apparatus, green ball (to protect siren).


The unit is a self-contained apparatus containing a battery, oscillator and a speaker that is small enough to be whirled around one's head on a length of cord. Switch on and whirl around one's head at a reasonable speed and an apparent change in frequency will be observed by the class. Due to safety concerns, this demo has now been enclosed in a Nerf ball in the event that the one operating the demo has poor grip.
