**1. Homework Statement**

It is just a conceptual doubt

**2. Homework Equations**

According to malus law intensity of light through polaroid is

I=(Io)cos^2(theta) where theta is the angle between axis of polaroid and incident light.

**3. The Attempt at a Solution**

But when Theta=0 then I=Io but in my book it is I=Io/2.

why??

and also is my diagram below correct?

--->(light)(I) [](polaroid) --->(I/2) [] --->(I/4) (theta=0 degrees for both polaroid)
