Vertically polarized light with intensity I0 is normally incident on

Vertically polarized light with intensity I0 is normally incident on an ideal polarizer. As the polarizer is rotated about a horizontal axis, 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 q for one complete rotation of the polarizer (0 ≤ q ≤ 360 °).
