Doppler Shift Calculator
Waves in a medium
Electromagnetic waves (with relativistic effects)
Transmitter velocity
Note: This velocity is relative to
the medium
and towards the receiver.
Receiver velocity
Note: This velocity is relative to the medium and towards the transmitter.
Wave velocity
Use velocity of
light in vacuum
sound in air
(m/s).
Note: This velocity is relative to the medium.
Note: Use the same units for all velocities.
Resulting Doppler shift
Note: This is the ratio of the observed frequency shift to the original frequency.
