Energy of photon emitted by electron in infinite square well

[sunshine1487]

HELP! I need to find the energy emitted by a photon if an electron is confined in an infinitely deep well. Can someone tell me what the hell to do please?! I'm desperate!

Thanks!

What exactly is the question? You haven't given enough information. And you need to show what you've tried so far if you want to get some help.

The wave function is given by psi=Nsin(n pi x/L).
Use that to find the eigenenergies.
