Problem- Unpolarized light whose intensity is 1.90 W/m2 is incident on the polarizer in the figure.
(a) What is the intensity of the light leaving the polarizer?
(b) If the analyzer is set at an angle of θ = 78o with respect to the polarizer, what is the intensity of the light that reaches the photocell?
