a. A relatively rare transition of the hydrogen atom emits a radio photon with with ? = 21 cm. This emission line is extremely important to astronomers for two main reasons: it cuts through most gas and dust without being absorbed and, although transition is rare, there is so much hydrogen in space that the 21 cm photons are themselves quite common. Suppose that one such photon from a distant galaxy is measured to have a wavelength of just 11...
