Question

9.19 Calculate the probability that an electron will be found (a) between x = 0.1 and 0.2 nm, and (b) between 4.9 and 5.2 nm in a box of length L = 10 nm when its wavefunction is y = (2/L)1/2 sin(2px/L). Hint: Treat the wavefunction as a constant in the small region of interest and interpret dV as dx.

9.20 Repeat Exercise 9.19, but allow for the variation of the wavefunction in the region of interest. What are the percentage errors in the procedure used in Exercise 9.19? Hint: You will need to integrate y2dx between the limits of interest. The indefinite integral you require is given in Justification 9.1.
