7.140. Interstellar Hydrogen Astronomers have detected hydrogen atoms in interstellar space in the n = 732 excited state. Suppose an atom in this excited state undergoes a transition from n = 732 to n = 731. a. How much energy does the atom lose because of this transition? b. What is the wavelength of radiation corresponding to this transition? c. What kind of telescope would astronomers need to detect radiation of this wavelength? (Hint: It would not be one designed to capture visible light.)
