A particle is confined to a one-dimensional box (an infinite well) on the x-axis between x = 0 and x = L. The potential height of the walls of the box is infinite.
 
  The normalized wave function of the particle, which is in the ground state, is given by (x) = sin , with 0  x  L. What is the probability of finding the particle between x = 0 and x = L/3?
  A) 0.20
  B) 0.22
  C) 0.24
  D) 0.26
  E) 0.28

Question 2

The probability density for an electron that has passed through an experimental apparatus is shown in the figure.
 
  If 4100 electrons pass through the apparatus, what is the expected number that will land in a 0.10 mm-wide strip centered at x = 0.00 mm?
 
  A) 140
  B) 1400
  C) 450
  D) 45
