Unpolarized light from an incandescent lamp has an intensity 176 Cd as measured by a light meter. What is the intensity reading on the meter when two ideal are inserted between the bulb and the meter with their axis of polarization making an angle of θ = 40.0° relative to each other? Express your answer in Cd. am having some trouble with this problem. Here's what I have so far: Known info: Io=28 Cd Theta= 6o There are two polarizers, so theta1=6 and theta2=6 Equations: I= Io/2 Malus' Law: I= Iocos^2theta Work: I used this to try and solve and it is wrong... I = 28/2 I=14 Then I = 28(cos6)^2 which = 27.7 (at theta1) but there are two polarizers so 27.7 becomes the new Io for theta2 I=27.7(cos6)^2 which =27.4 So you add them right? 27.7+27.4 which = 55.1? Where am I getting confused?
