Chapter 33, Problem Q33.20DQ
You are sunbathing in the late afternoon when the sun is relatively low in the western sky. You are lying Hat on your back, looking straight up through Polaroid sunglasses. To minimize the amount of sky light reaching your eyes, how should you lie: with your feet pointing north, east, south, west, or in some other direction? Explain your reasoning.

Two ideal polarizing sheets are stacked so that none of the incident unpolarized light is transmitted. A third polarizing sheet is slipped between the first two sheets such that 10 percent of incident light is transmitted through the stack. Find the angle of the third polarizing sheet. 19.6 degrees O 11.6 degrees 5.8 degrees 39.2 degrees.
Unpolarized light that has an intensity of I0 = 840 W/m^2 is incident on a series of polarizing filters as shown in Figure.
If the intensity of the light after the final filter is I3 = 84 W/m^2, what is the orientation of the second polarizer relative to the x axis (denoted q in the figure)? Enter the smaller possible angle between 0 and 90∘. Hint: cos(90−θ)=sinθ and 2sinθcosθ=sin2θ. (Express your answer to two significant figures.)
You are taking a photograph of a sunlit office building at sunrise, so the plane of incidence is nearly horizontal. In order to minimize the reflections from the building’s windows, you place a polarizing filter on the camera lens. How should you orient the filter? (i) With the polarizing axis vertical; (ii) with the polarizing axis horizontal; (iii) either orientation will minimize the reflections just as well; (iv) neither orientation will have any effect.
