Rydberg atoms have electrons that are in highly excited states. Because of their properties, Rydberg atoms have been proposed as a candidate for creating a quantum computer. Rydberg atoms can also be produced experimentally in the lab. Transitions among two Rydberg states result in photons at radio wavelengths. One of the longest wavelengths corresponds to a transition from n = 273 to n = 272. How many times larger is the diameter of a hydrogen Rydberg atom in the n = 273 state than the hydrogen atom in the ground state? Express your answer using two significant figures. Now determine the wavelength of the photon emitted if the atom transitions from n = 273 to n = 272. Express your answer in cm using two significant figures.
