Key Features
- Sound source unit on a motion track.
- Frequency indicator to follow the shift.
- Compares a stationary source with a moving one.
- Links to radar, astronomical red shift, ultrasound imaging and sirens.
Technical Specifications
| Specification | Value |
|---|---|
| Components | Sound source unit, motion track, frequency indicator |
| Body | Plastic, with sound generator system |

How It Is Used
Place the kit on a stable surface, switch on the sound source and move it towards and then away from the listener. Students compare the pitch with that of the stationary source and use this Doppler effect kit to explain frequency shift and relative motion. Avoid long exposure to loud sound.
Frequently Asked Questions
What does the Doppler Effect Kit show as the source moves?
The pitch heard changes as the source moves towards or away from the observer, showing the frequency shift caused by relative motion.
Where is the effect shown by the Doppler Effect Kit used in practice?
In radar systems, red shift in astronomy, medical ultrasound imaging and the changing pitch of a passing siren.
