Doppler effect for light Calculator

Calculates the Doppler shift in wavelength of light.

The forward angle of light source θ is set as 180 (recede), 0 (approach), 90 (laterally).

Velocity ratio to light v0/c
Doppler effect for light
The faster the light source recedes, the redder its color becomes.
