Question
Unpolarized light with intensity 200 W/m^2 travelling to the right, is incident on the left-most polarizer and goes through all three polarizers of the figure. The dotted lines are the axes of polarization of each polarizer
a) What is the intensity of light leaving the left-most polarizer?
b) If the middle polarizer has an axis of polarization θ2 = 75º clockwise from the vertical (viewed in the direction the light is travelling), what is the intensity of light leaving the middle polarizer?
c) If the right-most polarizer has an axis of polarization θ1 = 25º counterclockwise from the vertical (viewed in the direction the light is travelling), what is the intensity of light leaving the right-most polarizer?
