The rest wavelength is λ 0 This equation is not rendering properly due to an incompatible browser. is the difference between the measured wavelength of the line in the star’s spectrum and its wavelength in the lab. In this equation, Δ λ This equation is not rendering properly due to an incompatible browser. Δ λ / λ 0 = v r / c This equation is not rendering properly due to an incompatible browser. The following formula is then used to derive the radial velocity of the star: In practice, astronomers compare the wavelength of absorption lines in the spectrum of a star to the wavelength measured for the same lines produced in the laboratory (for example, the Balmer series lines of hydrogen). That is, the faster the source is moving, the more of a shift you will see.
