# Doppler Effect Red Shift Velocity Calculator

The difference in the wavelength of light due to relative motion between the light source and the observer is called as Doppler’s effect. The frequency observed by the observer will be lower and source transmitted frequency will be higher is called as Red shift frequency. Doppler effect red shift velocity calculator helps you to calculate the red shift velocity based on the speed of lights and wavelengths observed.

Code to add this calci to your website  #### Formula:

V = C × (1 - E / R) Where, V = Red-Shift Velocity C = Speed of Light from Source E = Emitted Wavelength R = Red-Shift Wavelength

### Example:

Calculate the red shift velocity having a 15 m/s of speed of light, 25 cm of emitted wavelength and 30 cm of red shift wavelength.

#### Solution:

Doppler effect of red shift velocity = 15 × ( 1- 25 / 30 )
= 2.5 m/s.
