Suppose that in Sample Problem 7.7, the orientation of the second and third filters are interchanged. Find the intensity of light emerging from each filter. Polarized light may also be produced at a particular angle of incidence called Brewster's angle or polarizing angle. At Brewster's angle, the reflected ray is almost completely polarized and is perpendicular to the refracted ray (figure 7-13). Using Snell's law and taking 90° 82 N1 = Nair=1.00 and n2=n (of the reflecting surface), the Brewster's angle is given by Fig. 7-12. At the polarizing angle 0, the reflected and refracted rays are perpendicular to each other. tan 0,=n. Eq. (7.14)

The movable mirror of a Michelson interferometer is attached to one end of a thin metal rod of length 23.3 mm. The other end of the rod is anchored so it does not move.

Show that if you have three polarizing filters, with the second at an angle of 45.0to the first and at third at an angle of 90.0to the first, the intensity of light passed by the first will be reduced to 25.0% of its value. (This is in contrast to having only the first and third, which reduces the intensity to zero, so that placing the second between them increases the intensity of the transmitted light.)
