Question

1.

(a) What is the Intensity of the light after it passes through Sheet 1 beforereaching Sheet 2.
(b) What is the Intensity of the light after it passes through Sheet 2?

(c) We assume the initial leftward moving electro-magnetic wave (before reaching sheet 1) is linearly polarized in the vertical direction with the electric field oscillating up and down parallel to the page. For the initial wave, suppose at a given location in space and moment in time, the electric field points vertically up. What direction is the magnetic field vector at that same location and instant of time, IN orOUT of the page. Explain your reasoning or any right hand rules you use.

Explanation / Answer

a) according to malus law= I= Io cos^2 Theta

I=41* cos^2 70

=41*0.117

=4.797 wb

b) I= 4.797 *cos^2 (90-40)

=4.797* cos^2 50

=1.98 wb

c) magnetic field is inward (IN) of the page according to right hand rule.
