Product Details
Doppler Rocket
Effectively teaches students the frequency shift concept and its rugged design allows for years of classroom use.
Description
The Doppler Rocket combines the elements of a toy with an audio Doppler shift to create an educational experience students won’t forget. The Doppler Rocket emits a true, sinusoidal sound waveform at a constant frequency of approximately 620 Hz. The circuit and speaker are housed in skinned foam that protects the unit during normal impacts. The circuit is powered by a 9 V battery. As the Doppler Rocket passes the students, they hear a noticeable shift in frequency. Velocities of 10 m/s can be easily achieved, resulting in a 20 Hz shift in frequency.
