1. The problem statement, all variables and given/known data
An electron is confined in a box where a = 60nm, b = 20nm, c = 35nm. For each of the first four quantum levels above the ground state give:

a) The quantum numbers
b) The speed of an electron trapped at that level
c) The wavelength of light needed to excite an electron from the ground state to that level.


2. Relevant equations
[tex]E_{n_1n_2n_3}=\frac{h^2}{8m}(\frac{n_1^2}{a^2}+\frac{n_2^2}{b^2}+\frac{ n_3^2}{c^2})[/tex]


3. The attempt at a solution
I don't know where to start with this problem. Can someone give me a hint how to begin? It would be greatly appreciated.
