An electron is trapped in an infinite square-well potential of width 0.6 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? (list in descending order of energy. enter 0 in any remaining unused boxes.)

E₁ = 1.042 eV

E₄₋₃= 7.29 eV      

E₄₋₂= 12.50 eV

E₄₋₁= 15.63 eV

E₃₋₂= 5.21eV

E₃₋₁= 8.34eV

E₂₋₁= 3.13eV

Explanation:

The energy in an infinite square-well potential is giving by:  

where, h: Planck constant = 6.62x10⁻³⁴J.s, n: is the energy state, m: mass of the electron and L: widht of the square-well potential      

The energy of the electron in the ground state, n = 1, is:  

The photon energies that are emitted as the electron jumps to the ground state is the difference between the states:
