Chapter 25, Problem 70PCE

An incident beam of light with an intensityl₀. passes through a polarizing filter whose transmission axis is at an angle θ to the vertical As the angle is changed from θ = 0 to θ = 90^° the intensity as a function of angle is given by one of the curves in Figure 25-43. Give the color of the curve corresponding to an incident beam that is (a) unpolarized, (b) vertically polarized, and (c) horizontally polarized.
