Problem 8
A one-dimensional infinite potential well locating between -0.5 nm to 0.5 nm and contains 10 electrons. It has 10 electrons inside. What is the least energy, in eV, the incident light must have in order to excite a ground-state electron (i.e., at the lowest n quantum value) in this system to the lowest higher state it can occupy when T=0?
(A) ~8.7 eV,
(B) ~13.6 eV,
(C) ~5.61 eV,
(D) ~13.2 eV,
(E) ~44.9 eV.
