A mercury atom is initially in its lowest possible (or ground state) energy level. The atom absorbs a photon with a wavelength of 185 nm and then emits a photon with a frequency of 4.924 x 10^14 Hz. At the end of this series of transitions, the atom will still be in an energy level above the ground state. Draw an energy-level diagram for this process and find the energy of this resulting excited state, assuming that we assign a...

A hydrogen atom in the ground state absorbs a 12.75 eV photon. Immediately after the absorption, the atom undergoes a quantum jump to the next-lowest energy level. What is the wavelength of the photon emitted in this quantum jump? Express your answer using four significant figures. I've seen this question before, but I'm looking the wavelength, not the energy, or n. Thanks!

The electron in a hydrogen atom falls from an excited energy level to the ground state in two steps, causing the emission of photons with wavelengths of 656.5 nm and 121.6 nm (So the in the first step the 656.5 nm photon is emitted and in the second step the 121.6 nm photon is emitted). What is the principal quantum number (ni) of the initial excited energy level from which the electron falls?
