Reference no: EM13488311

An electron in an infinite potential well (a box) makes a transition from the n = 3 level to the ground state and in so doing emits a photon of wavelengh 20.9 nm.

(1) what is the width of this well?

(2) What wavelength photon would be required to exite the electron from its original level to the next higher one?
