Astronomers have detected hydrogen atoms in interstellar space in the n = 732 energy level. Suppose an atom in this excited state emits a photon and undergoes a transition from n = 732 to n = 632. How much energy does the atom lose as a result of this transition? What is the frequency of this radiation? In which spectral region does this radiation lie?
