The Doppler Effect
Named after Austrian physicist Christian Doppler
- Proposed it in 1842
Apparent change in frequency of an object
- Appears higher when approaching
- Appears lower when moving away
- Appears higher when approaching
Examples
- Siren from an ambulance
- Sound from a passing race car
Object moving towards stationary observer
- Apparent frequency - f'
- f'=\(\frac{v}{v-vs}\)f
- Apparent frequency - f'
Object moving away from stationary observer
- Apparent frequency - f'
- f'=\(\frac{v}{v+vs}\)
- Apparent frequency - f'
v = speed of wave
- vs = velocity of source
- f = frequency of wave
- vs = velocity of source
