10,000 measurements are made of the energies of a particle in a box with infinite potential walla a distance L, apart. The results of the measurements are
E1 occurs 2000 times
E2 Occurs 5000 times
E3 occurs 3000 times
obtain the probabilitites of each of the measured energies and from this the coefficient of an expression of the tie dependent wave function
P(E1) = 2000/10000 = 2/5
P(E2) = 5000/10000 = 1/2
and P(E3) = 3000/10000 = 3/10
P(E1)+P(E2)+P(E3) = 1;
let
thus
thus
and
and
note that sum satisfies the completeness condition
thus wavefunction is
and time dependent wavefunction
if you wish to substitute the equations for
and for values of n = 1,2,3 you can.
