(Answered) A ground state h-atom absorbs a photon of wavelength 9491

Academics

A ground state H-atom absorbs a photon of wavelength 94.91 nm, and its electron attains a higher energylevel. 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.

a. What higher level did the electron reach? (Ans. n = 5)

b. What intermediate energy level did the electron reach? (Ans. n =3

c. What was the wavelength of the second photon emitted? (Ans. 1.02 x 10-7m)
