Suppose that an electron trapped in a one-dimensional infinite well of width 0.341 nm is excited from its first excited state to the state with n = 5.

1 What energy must be transferred to the electron for this quantum jump?

2 The electron then de-excites back to its ground state by emitting light. In the various possible ways it can do this, what is the shortest wavelengths that can be emitted?

3 What is the second shortest?

4 What is the longest?

5 What is the second longest?
