10. Three polarizing disks have planes that are parallel and centered on a common axis. The direction of the transmission
axis (dashed line) in each case is shown relative to the common vertical direction. A polarized beam of light (with its axis
of polarization parallel to the horizontal reference direction) is incident from the left on the first disk with intensity S, =
820 W/m2. Calculate the transmitted intensity if 0₁ = 21.0°, 0₂ = 34.0°, and 03 = 44.0°.

Given that 100 W/m? of a randomly polarized (unpolarized) light is incident normally on a stack of
ideal linear polarizers that are positioned one behind the other with the transmission axis of the first
vertical, the second at 30° from the vertical, the third at 60° from the vertical and the fourth at 90° from
the vertical axis. How much light emerges after each polarizer?
A system of three polarizing sheets is placed in the path of initially unpolarized light. The polarizing direction of the first sheet, P1, is parallel to the y-axis, that of the second sheet, P2, is 60o counterclockwise from the y-axis, and that of the third sheet, P3, is parallel to the x-axis.
Determine the fraction of the initial intensity Io of the light emerges from the system, i.e. ratio I0/I3.

Also, let the center disk be rotated on the common axis with an angular speed . Show that if unpolarized light is incident on the left disk with an intensity Imax, the intensity of the beam emerging from the right disk is I=116Imax(1cos4t) This result means that the intensity of the emerging beam is modulated at a rate four times the rate of rotation of the center disk.
