- Named after Austrian
physicist Christian
Doppler
- Proposed it
in 1842
- 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
- Siren from an
ambulance
- Object moving
towards stationary
observer
- Apparent frequency - f'
- f'=\(\frac{v}{v-vs}\)f
- f'=\(\frac{v}{v-vs}\)f
- Apparent frequency - f'
- Object moving away
from stationary
observer
- Apparent
frequency - f'
- f'=\(\frac{v}{v+vs}\)
- f'=\(\frac{v}{v+vs}\)
- Apparent
frequency - f'
- v = speed
of wave
- vs = velocity of
source
- f = frequency of
wave
- f = frequency of
wave
- vs = velocity of
source
