A sodium atom in one of the states labeled “Lowest excited levels” in Fig. remains in that state, on average, for 1.6 * 10-8 s before it makes a transition to the ground state, emitting a photon with wavelength 589.0 nm and energy 2.105 eV. What is the uncertainty in energy of that excited state? What is the wavelength spread of the corresponding spectral line?
A hydrogen atom is at rest, in the second excited state, when it emits a photon of energy 12.1 eV.  What is the speed of the ground-state hydrogen atom when it recoils due to the photon emission? What is the kinetic energy of the recoiled particle?
A) What is the approximate wavelength emitted from helium represented by the bright yellow emission line below?  What is it's frequency in HZ and energy in eV? (1 eV= 1.6 x 10-19 joules).  B) If the excited helium electron that emits a yellow photon in this line starts with a potential energy of 8 eV, what is the potential energy of the electron afterwards? Assume that the emission of a yellow photon is allowed by the laws of quantum mechanics. Also don't worry about the other electron.
