A monochromatic beam of light is absorbed by a collection of ground-state hydrogen atoms in such a way that six different wavelengths are observed when the hydrogen relaxes back to the ground state.Required:(a) What is the wavelength of the incident beam? Explain the stepsin your solution.(b) What is the longest wavelength in the emission spectrum ofthese atoms? To what portion of the electromagnetic spectrum and towhat series does it belong?(c) What is the shortest wavelength? To what series does itbelong?
