This is a simulation of what happens when unpolarized light, with an intensity of 800 W/m2 is incident on a sequence of three polarizers. The light is traveling in the +x direction and the polarizers are located at x = 10 cm, x = 20 cm, and x = 30 cm.
Use the sliders to adjust the angle of the transmission axis of each polarizer. The graph shows the intensity of the light at different locations along the x axis. The lines after each polarizer show the direction the light is polarized in. The incident light has multiple lines to show that it is unpolarized.
