Homework Statement
A monatomic gas is illuminated with visible light of wavelength 400nm. The gas is observed to absorb some of the light and subsequently emit visible light of both 400nm and 600nm. The initial state is -5.0 eV and the ionized atom (continuous energy levels) is 0 eV.
a) Draw the situation.
b) If the inital state of the atoms has energy -5 eV, what is the energy of the state to which the atoms were excited by the 400nm light?
c) At which other wavelength(s) outside the human visible range do these atoms emit radiation after they are excited by the 400nm light?
Homework Equations
The Attempt at a Solution
I wasn't in class when my teacher covered the material, and it's not in the book.
Can someone at least just get me started, explaining the drawing and what equations I should use?
