Consider a particle in a one-dimensional infinite square well with width a, centered at a/2. The normalized energy
eigenstate wave functions are Vn(x) with energies En(n-1 is the ground state). The particle starts in a state given by
(x,r=0)= sqrt(4/5)w1(x)+sqrt(1/5) w2(x).
Assume the particle has been re-prepared in state v3(x). You then make a position measurement with high accuracy. After
this position measurement, you immediately re-measure the energy. At this point, what value(s) could you get for the
energy of the particle?
A.
E2
B.
E3
C.
E2 or E3
D.
Any En
E. Any continuous E
O A
B
