Doppler Effect Frequency Shift Calculator
Enter the source frequency, velocities and speed of sound to compute the observed frequency using the Doppler effect.
CalcSimpler Examples
- 500 Hz, observer 10 m/s, source 20 m/s ⇒ 546.44 Hz
- 1000 Hz, observer 0 m/s, source 30 m/s ⇒ 1095.85 Hz
FAQ
How are directions handled?
Velocities toward each other are positive; use negative values when moving apart.
Can I use other wave speeds?
Yes, replace the speed of sound with the speed of the wave in the medium.
What if source velocity equals wave speed?
The formula approaches infinity; ensure source speed is below wave speed.
