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 λphoton = 2280 nm. When it falls from n-1 to n-2, it emits a photon of wavelength λphoton = 3192 nm.
1) What is the energy of the n to n-1 photon in eV?
En to n-1 =
2) What is the energy of the n-1 to n-2 photon in eV?
En-1 to n-2 =
3) What is the initial value of n?
ninitial =
4) What is the width, L, of the well in nm?
L =
5) What is the longest wavelength of light, λlongest, the well can absorb in nm?
λlongest =
