a. Where is the wave located?
b. Keep k2 the same and choose k1 = 8.0 rad/m. Now, there is a localized packet. What is the uncertainty in x (measure the distance from one zero amplitude to the next)? What is the uncertainty in k (Δk = |k1 − k2|)? What is the uncertainty in x
and the uncertainty in kfor part (a)?
c. Find the probability that the particle is located in the left-hand side of the region (0 > x > 0.5).
d. Calculate the expectation value of x---the probability density is given by 2*sin2(pi*x).
