The hydrogen alpha has a 658.28 nanometer wavelength. The Andromeda galaxy is approaching the Milky Way galaxy at about 110 kilometers per second (km/s). Earth is located on the Milky Way galaxy's Sagittarius spiral which arm orbits the galactic core resulting in the earth and the Andromeda galaxy approaching each other at a relative velocity of 300 km/s. What is the shifted wavelenght of the Hydrogen alpha light emitted by stars in the Andromeda as viewd from Earth?
