    Can anyone tell me what the doppler wavelength shift equation is?

    I'm trying to find the wavelength shift for light with a certain wavelength that is emitted from the sun. Is there a different kind of equation for light wavelength shifts?

    There's the relativistic Doppler shift, [tex] \lambda= \lambda _0 \sqrt{ \frac{1+v}{1-v}} [/tex]
    But if you're only making the correction of the speed Earth to Sun, the classical formula is enough, I think
