The Doppler Effect
Investigating the apparent change in frequency of a wave due to relative motion between source and observer.
Key Questions
- Explain the Doppler effect using examples of sound and light waves.
- Predict the change in perceived pitch of a siren as it approaches and recedes.
- How would an engineer apply the Doppler effect to develop high-precision speed detection systems?
