An electron is in an infinite square well (a box) that is 8 nm wide. The electron makes a transition from the n = 3 to the / = 2 state, what is the wavelength of the emitted photon?(h = 6.626 x 10-34 J . s, m .| = 9.11 x 10 kg. 1 ev = 1.60 x 10-19) @ 2.7*104 mm Q 1.6*10" nm 4.2x10# nm 3.1x10" nm 2x 10# nm
