1 nm. Given: Mass of electron, m = 9.1 x 10^-31 kg Uncertainty in position, Δx = 0.1 nm = 0.1 x 10^-9 m Using the uncertainty principle, Δp * Δx ≥ h/4π Δp = h/(4πΔx) Show more…

An electron is confined to a box the size of a small atom, $0.10 \mathrm{nm}$ across. (a) What's the uncertainty in the electron's momentum? (b) Suppose the momentum is just equal to the minimum uncertainty value you computed in part (a). What's the electron's energy? What wavelength photon would have the same energy?
