1. Consider a nonpolarized light with an intensity of 9.2 W/m2. The rays of this light are directed toward two polarizing elements whose transmission axes form an angle of 75. How much is the intensity of light from the second film? 2. Two polarizers were set up so that no light gets through them. Suppose a third sheet is inserted between the first two so that the transmission axis will form an angle 0 with the transmission axis of the first sheet. Nonpolarized light with an intensity of Io is incident on the first sheet. What is the intensity of the light transmitted through all three sheets if 0 has a value of 45 at one instance and 30 at another instance? 3. Nonpolarized light having an intensity of 3.4 W/m is incident on two polarizers with transmission axes forming an angle of 15. What is the intensity of light emerging from the second polarizer? 50
