(10%) Problem 8: Suppose Iy s the intensity of light transmitted through two polarizing filters with axes at a relative angle , and [; is the intensity when the axes are at a relative angle 90.0%-8. A& What was the original mtensity Jj. assuming the light started out unpolarized? (10%) Problem 9: Unpolarized light of intensity Iy = 750 W/m? is incident upon two polarizers. The first has 1ts polarizing axis vertical, and the axis of the second is rotated & = 75 from the vertical. &3 Ray Randomized Variables Dhirection & 25% Part (a) Express the intensity of the light after 1t passes through the first polarizer, I}, in terms of I, and &
