In a double Stern-Gerlach experiment, spin 1/2 particles emerge from the first magnet as two separate beams. The portion of the separated beam corresponding to Sz =(+h bar/2) is then passed through a second identical magnet whose z axis is rotated by an angle theta with respect to the first magnet.
(a) How many beams emerge from the second magnet?
(b) What probability is associated with the beam (beams) that emerge from the second magnet?
