18M.1.HL.TZ1.29

Two lines X and Y in the emission spectrum of hydrogen gas are measured by an observer stationary with respect to the gas sample.

                                                       M18/4/PHYSI/HPM/ENG/TZ1/29_01

The emission spectrum is then measured by an observer moving away from the gas sample.

What are the correct shifts X* and Y* for spectral lines X and Y?
