Unpolarized light passes through six successive Polaroid sheets each of whose axis makes a 59 degree angle with the previous one.

What is the intensity of the transmitted beam, I/Io?

    After the light passes through the first Polaroid, it's intensity is 1/2Io. Now the light is polarized

    After the second sheet, it is now

    1/2I0*((cos(59))^2)

    After the third sheet it is

    1/2I0*((cos(59))^2)*((cos(59))^2)
    . .

    Do this up to the 6th sheet, and divide by I0
