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
