A ground-state H atom absorbs a photon of wavelength 94.91 nm, and its electron attains a higher energy level. The atom then emits two photons: one of wavelength 1281 nm to reach the ground state and a second to reach in intermediate level.
1. Determine at what higher level did the electron reach?
2. Determine at what intermediate level did the electron reach?
3. Determine the wavelength of the second photon emitted?
