Doppler Shift Calculator

Formula : λƒ = v usƒ0 .

Enter the unknown value as ‘ x.’

Wave Velocity (v) = m/s

Source Velocity (us) = m/s

Source Frequency (ƒ0) Hz

Wavelength in Front of a Moving Source (λƒ)

Answer =


Doppler Shift Calculator is a free online tool that displays the wavelength when the observer is in motion relative to the wave source. BYJU’S online Doppler shift calculator tool performs the calculation faster, and it displays the wavelength in a fraction of seconds.

How to Use the Doppler Shift Calculator? 

The procedure to use the Doppler shift calculator is as follows:

Step 1: Enter the wave velocity, source velocity, source frequency and x for the unknown in the input field

Step 2: Now click the button “Calculate the Unknown” to get the result

Step 3: Finally, the wavelength in front of the moving source will be displayed in the output field

What is Meant by Doppler Shift?

In Physics, Doppler shift also known as the Doppler effect is defined as the change in the frequency or the wavelength of the waves with respect to the observer who is in the moving state relative to the wave source. The Doppler effect is applicable when the velocity of the observer and the source of sound are always less than the velocity of the sound. The Doppler shift equation is as:

f=f0 [(v+vr)/(v+vs)]


f is the observed frequency

f0 is the emitted frequency

V is the velocity of waves in the medium

Vr is the velocity of the receiver

Vs is the velocity of the source.
