Question

A quantum system is described by a wave function (r) being
a superposition of two states with different energies E1 and E2:
(x) = c191(r)e iEit/h+ c292(x)e¯iE2t/h.
where ci = 2icz and the real functions p1(x) and p2(r) have the following
properties:
vile)dz = ile)dz = 1,
"0 = rp(x)T#(x)l&
p1(x)92(x)dx% D0.
Calculate:
1. Probabilities of measurement of energies E1 and E2
2. Expectation valuc of cnergy (E)

An electron is trapped in a region between two infinitely high energy barriers. In the region between the barriers the potential energy of the electron is zero. The normalized wave function of the electron in the region between the walls is ψ(x) = Asin(bx), where A=0.5nm1/2 and b=1.18nm-1. What is the probability to find the electron between x = 0.99nm and x = 1.01nm.
