An electron is trapped in a region between two perfiectly rigid walls (which can be regarded as infinitely high energy barriers). in the region between the walls the potential energy of the electron is zero. the (normalized) wave function of the electron in the region between the walls is ψ(x) = a sin br where a = 0.50 nmi/2 and b 1.18 nm (a) by substituting into the schrödinger equation, find the energy of the electron in this state of motion. (b) what is the probability to find the electron betweenx 0.99 nm andx 1.01 nm?
