1. Plane-polarized light is incident on a single polarizing disk, with the direction of E0 parallel to the direction of the transmission axis. Through what angle should the disk be rotated so that the intensity in the transmitted beam is reduced by a factor of
(a) 3.00,
(b) 5.00,
(c) 10.0?
2. Three polarizing plates whose planes are parallel are centered on a common axis. The directions of the transmission axes relative to the common vertical direction are shown in Figure P24.53. A linearly polarized beam of light with plane of polarization parallel to the vertical reference direction is incident from the left onto the first disk with intensity Ii _ 10.0 units (arbitrary). Calculate the transmitted intensity Ifwhen ?1= 20.0°, ?2= 40.0°, and ?3= 60.0°.
