Three polarizing disks whose planes are parallel and centered on common axis. The directions of their transmission axes relative to the vertical are respectively: θ1 = 39o clockwise, θ2 = 20o counter-clockwise, and θ3 = 23o clockwise. A beam of light polarized along the vertical is incident onto the first polarizer with an intensity of I0 = 30.0 W/m². Calculate the transmitted intensity through all three polarizers.

Three polarizing disks whose planes are parallel and centred on common axis. The directions of their transmission axes relative to the vertical are respectively: θ1 = 15o, θ2 = 38o, and θ3 = 61o. A beam of light polarized along the vertical is incident onto the first polarizer with an intensity of I0 = 10 W/m². Calculate the transmitted intensity through all three polarizers. The answer is 6.7, but I am unable to get that.

1. Answer these following questions on polarizers and light. a. A polarized light is incident on several polarizing disks whose planes are parallel and centered on common axis. Suppose that the transmission axis of the first polarizer is rotated 24° relative to the axis of polarization of the incident light, and that the transmission axis of each additional analyzer is rotated 24° relative to the transmission axis of the previous one. What is the minimum number of polarizer needed (whole...
