Consider the wavefunction: particle in an infinite well of width L, with
wavefunction given as a superposition of two energy eigenstates, with quantum numbers n=1 and m=2. Show that the Energy-Time uncertainty principle, applied to the time it takes <x> to change by an
amount σx, indeed holds true in this case.
soo, i have <x> and σx, and i guess i can find σE by doing sqrt(<E>^2 + <E^2>), i just don't see how I'm supposed to use those values for the uncertainty principle which says ΔE*Δt< hbar/2.
help?
