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 an intermediate level, and a second to return to the ground state.
Rydberg constant = R = 1.096776 × 107 m^?^1h = 6.626 x 10-34 J.sc = 2.998 x 108 m/s
1. What higher level did the electron reach?
2. What intermediate level did the electron reach?
3. What was the wavelength of the second photon emitted?
