The Doppler effect describes frequency change when a source and observer are in relative motion. Sound pitches higher when approaching and lower when receding.
Formule
f' = f × (v ± v_observer) / (v ∓ v_source)
Stapsgewijze handleiding
- 1Enter source frequency and speed
- 2Enter observer and source velocities
- 3Apply Doppler formula with correct sign conventions
Uitgewerkte voorbeelden
Invoer
f = 440 Hz, source approaching at 10 m/s, v = 340 m/s
Resultaat
f' ≈ 454 Hz
Observed frequency increases
Veelgemaakte fouten om te vermijden
- ✕Wrong sign conventions for approaching/receding
- ✕Using ground speed instead of relative speed
