13. The probability that the electron is found in any interval is given by Pd x = z ψ 2 , where the integral is over the interval. If the interval width x is small, the probability can be approximated by P = | | 2 x , where the wave function is evaluated for the center of the interval, say. For an electron trapped in an infinite well of width L , the ground state probability density is 2 2 2 = F H G I K J L x L sin , π so P x L x L = F H G I K J F H G I K J 2 2 . π (a) We take L = 100 pm, x = 25 pm, and
