Unformatted text preview: Calculate p and 2 p for this system by using the form of the momentum operator in position space. Notice that there is another way to obtain 2 p in this case, using the relation between the square of the momentum and the total energy (which is known for every value of n ). Use this observation to check your result. c) Use your results to find the uncertainty p ∆ in momentum and show that / 2 x p ∆ ∆ ≥ h for all values of n , consistent with the uncertainty principle....
