Unpolarized light is incident on a series of polarizing disks. We have three polarizers A, B and C have transmission axes that make angles of 30, 90 and 180 degrees, respectively, measured CW from the vertical y-axis. You want to maximize the relative transmission and can place them in any order. What is the maximum possible relative transmission (is. Final/I0) passing through a series of all three polarizers

    Formula for intensity of light after transmission for unpolarised light is

    I₀ / 2, We shall take up 180 degree disk first.

    For second transmission, the formula is

    I = I₀ Cos²θ, θ is angle between axis of polarizer and axis of vibration.

    If we take up 30 degree polariser

    I = I₀ / 2 Cos² (180 - 30)

    =.375 I₀

    For third transmission

    I_ final =.375 I₀ x cos (90 - 30)

    =.1875 I₀

    Final/I₀ =.1875
