Electron in a box - calculate the spring constant

[shimph]

Homework Statement

Electron in a box has 2 sequential energy levels of 1.5 eV and 2.1 eV
Calculate the spring constant

Homework Equations

E[n]=n^2*E[0]
Therefore, 2.1/1.5 = 1.4 = (6^2)/(5^2) and the quantum levels are 5 and 6
E[0] = (h^2)(pi^2)/2(m)(L^2)

The Attempt at a Solution

What is the "spring constant" for the wave equation??

I think the question is connected to the time dependence of the wave function, but I am not sure...
