For objects moving a speeds well below the speed of light there is a simple relationship between the speed of the object, the shift in the wavelength of the light emitted by the object, and the unshifted wavelength of the light (what the wavelength would be if the object were not moving). This equation computes that speed based on the other two numbers.
