- Unpolarized light passes through two ideal Polaroid sheets. The axis of the first is vertical and the axis of the second is at 40.0° to the vertical. What fraction of the incident light is transmitted? 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 the figure below. 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 I₁ = = 11.0 units (arbitrary). Calculate the transmitted intensity I, when 0₁ = 21.0°, 0₂ = 41.0°, and 03 = 59.0°.
