Doppler Effect Red Shift Wavelength Calculator

The increase or decrease in the observed frequency in comparison with that emitted from the source is called Doppler effect for light. If the source light travels away from the observer means then it is called red shift frequency. Doppler effect red shift wavelength calculator calculates the red shift frequency by entered values of emitted frequency, velocity away from the observer and speed of light. This online calculator will fetch the results in the fraction of seconds.

Formula:

L = (E × C) / (C - V) Where, L = Observed Red-Shift Wavelength E = Emitted Wavelength C = Speed of Light From Source V = Velocity Away from You

Example:

Calculate the red shift wavelength, for the emitted frequency of 30 cm, velocity of 20 m/s and speed of 25 m/s.

Solution:

Doppler effect red shift wavelength= (30 × 25) / (25 – 20)
= 150 cm
