Vertically polarized light with intensity Io is normally incident on an ideal polarizer. As the polarizer is rotated, the intensity I of light transmitted through the polarizer varies with the orientation of the polarizer (Θ), where Θ = 0 corresponds to a vertical transmission axis. Sketch a graph of I as a function of Θ for one complete rotation of the polarizer (0≤ Θ≤ 360°).
