Doppler Effect Demo, Electronic
Safely and effectively demonstrate the Doppler effect! Swing this battery-operated buzzer over your head from its tethered string. Students will quickly observe a significantly higher pitch when it moves toward them and a lower tone when it moves away. Sound source is loud enough to easily be heard at the back of a class- room. Or add extra long string to super-size the demonstration, and swing it in a large gymnasium. Instructions, buzzer and 3 feet of string are provided. Requires 9-V battery, available separately.
