Use our Doppler Effect Blue Shift Wavelength Calculator to determine the observed wavelength when a light source moves towards an observer. Input the emitted wavelength and relative velocity to see the blue-shifted result instantly. Perfect for astronomy students, physicists, and space enthusiasts seeking to understand redshift and blueshift phenomena.
Formula:
The formula for the observed (blue-shifted) wavelength (λobs) is:
λobs = λemitted × √((1 - v/c) / (1 + v/c))
Where:
- λobs = Observed Wavelength (m or nm)
- λemitted = Emitted Wavelength (m or nm)
- v = Relative Velocity of Source (m/s)
- c = Speed of Light (299,792,458 m/s)
