Physics

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

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

En to n-1 =

2) What is the energy of the n-1 to n-2 photonin 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=
