| - | Doppler Effect Classes Used: PHYS 101, PHYS 153, ASTR 101 | + | Consists of an aluminum tube with a speaker, 3kHz frequency generator, and 9V battery mounted inside a large green foam ball (which has been reinforced with duct tape). A string with a rubber handle is attached to one end of the cylinder. |

| ===== Setup ===== | ===== Setup ===== | ||
| - | + | 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 green foam ball in the event that the one operating the demo has poor grip or something else goes wrong. | |
