Mg+ ions emit a doublet (2929 nm, 2936 nm) when undergoing 4s->3p transition and another doublet (2803 nm, 2796 nm) when undergoing a 3p->3s transition. Calculate the ratio of the number of Mg(+) ions in the 4s excited state to the number of ions in the ground state in the arc cor of a DCP source (~8000k). Use the average wavelengths for transitions in your calculations.

A sample of hydrogen atoms is irradiated with light with a wavelength of 89.0 nm, and electrons are observed leaving the gas. If each hydrogen atom were initially in its ground level, what would be the maximum kinetic energy in electron volts of these photoelectrons? A few electrons are detected with energies as much as 10.2 eV greater than the maximum kinetic energy calculated in part A. How can this be?
