If a wavelength is not the initial then it must be the final wavelength. The equation shows the shift in wavelength of the scattered photon with reference to the photon scattering angle. The constants in front of the equation combine to have a unit of length. The value is 2.426 picometers and is known as the Compton wavelength.
