How do polarized sunglasses reduce glare? Which direction is the axis of polarization in pair of polarized sunglasses? Imagine you are at eye level with the light coming at you. Consider the Figure showing "partially polarized" light coming from the laser. Note that the intensity of the light is greater in one direction (i.e. up and down, vertical to the tabletop) as compared to the other direction (i.e. left and right, horizontal to the tabletop). Think of the total intensity as the hypoteneuse of the two arrows shown. Sketch the total intensity and the relative vertical and horizontal intensities of polarization after the laser light passes through the 45 degree polarizer. Next the light reflects off of the non-conducting surface (so that the laser beam remains horizontal to the tabletop, i.e. this is the "plane of incidence). For the case of the angle of incidence equals Brewster's angle, sketch the total intensity and the relative vertical and horizontal intensities of polarization after the laser light reflects off of the non-conducting surface. Label the relative intensities as the s-polarized light or p-polarized light. The Light Sensor records total light intensity reaching the detector. The total light intensity form part b) will be recorded in your experiment; however you will also record the total light intensity after inserting an "analyzing polarizer" just before the light reaches the detector. The analyzing polarizer's transmission axis is horizontal. For the set-up as described in b) above what is the total intensity of the light teaching the detector with this analyzing polarizer in the beam path?
