# Doppler Effect Blue Shift Wavelength Calculator

A variation in the frequency of light waves as the source and the observer moves towards or away from one another is called as Doppler Effect. When the shift in the visible light is observed towards the blue end of the spectrum or high frequencies then it is called as the blue shift of Doppler effect. This online Doppler effect blue shift wavelength calculator helps you to calculate the observed blue shift wavelength for the entered input values.

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

L = (E × C) / (C + V) Where, L = Observed Blue-Shift Wavelength E = Emitted Wavelength C = Speed of Light from Source V = Velocity Towards You

### Example:

Calculate the blue shift wavelength for the emitted wavelength of 21 m, velocity of 18 m/s and speed of 15 m/s.

#### Solution:

Doppler effect of blue shift wavelength = (21 × 15) / (15 + 18)
= 9.5455 m
