Homework Statement
An electron is trapped in an infinite square-well potential of width 0.5 nm. If the electron is initially in the n=4 state, what are the various photon energies that can be emitted as the electron jumps to the ground state?
Homework Equations
ΔE=13.6(1/nf2-1/ni2)
En=hbar2n2∏2/(2mL2)
The Attempt at a Solution
Im not quite sure if this is a trick or not, but I thought that I did not need the energy equation for the 1-D infinite well, En, but just needed to use the ΔE equation and do n=4->n=1. Or do I also need to find the energy at n=4 and n=1 and show those as well?
