a) For the single well to the accuracy that you can read the energy level diagram, what is the energy
of the ground state? (you need to be within 0.01 eV of the correct answer)
E₁ = eV      

and first excited state?
E₂ = eV        

b) For the double well to the accuracy that you can read the energy level diagram, what is the separation of the ground state doublet? (you need to be within 0.001 eV of the correct answer)

DE = eV    

c) If the separation between the wells, D, were increased from 5 nm to 6 nm, would the separation of the ground state doublet increase or decrease?
    

f) With respect to the point x = 14.5 nm, the midpoint of the region between the two wells, is the lowest level of the ground state doublet an even function or an odd function? (That is, is it the red or blue curve in the graph above?)
    

The two graphs below show the wave functions of the triple well. The graph with solid curves shows the wave functions of the ground state triplet. The graph with dotted curves shows the wave functions of the first excited state.

g) Using the key,

1 = solid red ___
2 = solid green ___
3 = solid blue ___
4 = dotted red .....
5 = dotted green .....
6 = dotted blue .....
