A hydrogen atom is in its ground state (n, = 1) when a photon impinges upon it.
The atom absorbs the photon, which has precisely the energy required to raise the atom to the n, = 3 state.
(a) What was the photon's energy (in eV)?
12.089
ev
(b) Later, the atom returns to the ground state, emitting one or more photons in the process. Which of the following energies
describes photons that might be emitted thus? (Select all that apply.)
O 13.6 ev
O 1.89 eV
V 12.1 eV
O 10.2 ev
There are two ways a hydrogen atom in the n, = 3 state can end up in the ground state. In the first, all of the energy goes
into one photon and the electron moves directly into the ground state. (What would be the energy of that photon?) In the
other, the electron "descends" in two stages, each accompanied by the emission of a photon. (What would be the energies
of those two photons?)
PROBLEM: The lifetime of a nucleus in an excited state is 10-12s. Calculate the probable
uncertainty in the energy and frequency of a y-ray photon emitted by it.
A light detector has an area of 3.1m2 and absorbs 53.9% of the incident light, which is at wavelength 682.3nm. The detector faces an isotropic source, 2.1m from the source. If the detector absorbs photons at the rate of exactly 6photons/s , at what rate( in photons/s) does the emitter emit light?
