Doppler Effect Calculator

This Calctown Calculator calculates the observed frequency using the doppler effect.

Please note; relative velocity of the receiver to the medium is positive if the receiver is moving towards the source (and negative in the other direction). Relative velocity of the source to the medium is positive if the source is moving away from the receiver (and negative in the other direction).

where

f = observed frequency

f₀ = emitted frequency

v_x = velocity of receiver relative to medium

v_s = velocity of source relative to medium

c = velocity of waves in the medium
