Question

An electron is trapped in a square well of unknown width, L. It starts in unknown energy level, n. When it falls to level n-1 it emits a photon of wavelength λ_photon = 2280 nm. When it falls from n-1 to n-2, it emits a photon of wavelength λ_photon = 3192 nm.

1) What is the energy of the n to n-1 photon in eV?

E_{n to n-1} =

2) What is the energy of the n-1 to n-2 photon in eV?

E_{n-1 to n-2} =

3) What is the initial value of n?

n_initial =

4) What is the width, L, of the well in nm?

L =

5) What is the longest wavelength of light, λ_longest, the well can absorb in nm?

λ_longest =
