Physics

Consider how the intensity of light changes as it passes betweentwo Polaroid disks at different angles to each other. (For thisscenario, suppose that the polaroid closest to the light sourceremains fixed with the zero degree marking pointing straight up.Therefore, the second Polaroid disk is the one being rotated, andthe angles for the graph should be the angle between the zerodegree marking of the first disk and the position of the seconddisk. )

a. With intensity on the y axis, and angle in 45 degreeincrements on the x axis, sketch a graph of how the intensity of alight varies under various orientations of the two disks.

b. What is the mathematical relationship here? Explain how youarrived at this conclusion.

c. Based on the fact that the intensity of a light wave isproportional to the square of the electric field magnitude, explainwhy the transmitted intensity should have this mathematicaldependence on the angle.
