Doppler Rocket

Product Code: WA-9826

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.


Features

  • Rugged: Skinned foam protects the unit during classroom use.
  • Multi-Function Handles: The rope of the Doppler Rocket can be wound around the handles for easy storage.
  • Handle Cushions: Cushions prevent the Doppler Rocket from hitting the students’ hands as they propel the rocket across the room.
  • Low Power Consumption: One 9V battery provides several years of typical use.

Applications

  • Fly It Horizontally
  • Swing It Overhead
  • Play Catch
