Multiple choice
An electron in a 1D infinite square well of width L=1L = 1 nm is in an equal superposition of the n=1n=1 and n=2n=2 states, so ⟨E⟩=(1/2)E1+(1/2)E2\langle E\rangle = (1/2)E_1 + (1/2)E_2 with En=n2π2ℏ2/(2mL2)E_n = n^2 \pi^2 \hbar^2/(2 m L^2). Using ℏ=1.05457×10−34\hbar=1.05457\times10^{-34} J·s, m=9.10938×10−31m=9.10938\times10^{-31} kg, 11 eV=1.60218×10−19=1.60218\times10^{-19} J, what is the expected energy ⟨E⟩\langle E\rangle in eV?
