Battery tied to a string
Battery and Foam Ball

 

Code Number: 3B40.10

Demo Title: Doppler Effect - Buzzer and String

Condition: Excellent

Principle: Doppler Effect on Sound Waves

Area of Study: Oscillations & Acoustics

Equipment: 

9 Volt Battery Tied to a String, Piezo Buzzer to Attach to 9 Volt Battery, and Foam Ball.

Procedure:

Attach the Piezo buzzer to the 9 volt battery that is tied to the string.  Swing the unit overhead and listen to the effect.  You can also put a battery into the foam ball unit and either swing that around overhead or toss it back and forth across the room.
