Question

     (psi = sqrt{2/L}sin(npi x/L))          (Delta o = sqrt{(ohat^{2})-(ohat)^{2}{}})          (sigma^{2}_{p}  =  (p^{2})-(p)^{2} and   sigma^{2}_{x} = (x^{2})-(x)^{2})     a) The particle-in-a-box wavefunction is shown to the right. Calculat ethe uncertainity in x and the uncertainty in p, where the uncertainty in a given observable is calculated from the equation above with sigma and momentum operators.

where (o-hat^2) is the expectation value of the square of the operator and (o-hat)^2 is the square of the expectarrtion value of the operator.

b) from the answer show that the uncertainties in x and p follow the heisenberg uncertainty principle: which is is delta(p)delta(x) is greater than or equal to h-bar over 2
