A ground-state hydrogen atom absorbs a photon of wavelength 97.35 nm, causing the electron to jump to a higher energy level. Finally a second photon is emitted when the electron returns from the intermediate level to the ground state. This same atom then emits a photon of wavelength 1878nm and the electron falls back to an intermediate energy level.
1. Determine the wavelength of the second photon emitted.
2. Determine the quantum number of the intermediate level?
