Question

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 I_i = 11.0 units (arbitrary). Calculate the transmitted intensity I_f when θ₁ = 19.0°, θ₂ = 41.0°, and θ₃ = 65.0°. Hint: Make repeated use of Malus's law.
I_f =  units
