An electron is confined to a box the size of a small atom, 0.12nm across. ?p, the uncertainty in the electron's movement, = 4.4*10^-25 kg*m/s.
1. Suppose the momentum is just equal to the minimum uncertainty value you computed in part A. What's the electron's energy? K=?
2. What wavelength photon would have the same energy?
