Unpolarized light of intensity i0 = 950 w/m2 is incident upon three polarizers. the axis of the first polarizer is vertical. the axis of the second polarizer is rotated at an angle θ = 55° from the vertical. the axis of the third polarizer is horizontal.
(a) what is the intensity of the light after it passes through the first polarizer?
(b) what is the intensity of the light after it passes the second polarizer?
(c) what is the intensity of the light after it passes through the third polarizer?
(d) write an equation for the intensity of light after it passes through all three polarizers in terms of the intensity of unpolarized light entering the first polarizer io and the angle of the second polarizer relative to the first, given that the first and third polarizer are crossed (90 degrees between them).
(e) what is the smallest angle, from the vertical, that the second polarizer could be rotated such that the intensity of light passing through all three polarizers is 28 w/m^2?
