![]() The axis of the third polarizer is horizontal. The axis of the second polarizer is rotated at an angle 0 = 55° from the vertical. The axis of the first polarizer is vertical. ![]() (7%) Problem 14: Unpolarized light of intensity lo= 1150 W/m2 is incident upon three polarizers. ![]() A 20% Part (e) What is the smallest angle 02, in degrees, from the vertical that the second polarizer could be rotated such that the intensity of light passing through all three polarizers is 13'= 52 W/m2? Use trigonometric identities to simplify and give the results in terms of a single trigonometric function of p = 20. A 20% Part (e) What is the intensity in W/m² of the light after it passes through the third polarizer? A 20% Part (d) Write an equation for the intensity of light after it has passed through all three polarizers in terms of the intensity of unpolarized light entering the first polarizer lo and the angle of the second polarizer relative to the first, given that the first and third polarizers are crossed (90° between them).
