Polarized sunglasses reduce glare by Select one: O a. making everything look darker. b. blocking light waves that aren't lined up with the polarizer axis. O c. reflecting light waves that are lined up with the polarizer axis. O d. redshifting light waves that are not lined up with the polarizer axis. Clear my chojce

Unpolarized light, of intensity Io is incident on a pair of polarizers as shown below. The trans- mission axis of the first polarizer is vertical. The transmission axis of the second polarizer is unknown. Unpolarized light, intensity lo X Observer Polarizers (a) What should be the orientation of the second polarizer such that no light reaches the observer. If this is not possible, say so explicitly. (b) What should be the orientation of the second polarizer such that light of intensity Io/2 reaches the observer. If this is not possible, say so explicitly.

A 6.0 mW vertically polarized laser beam passes through a polarizing filter whose axis is 75° from vertical. What is the laser-beam power after passing through the filter?A. 0.40 mW        B. 1.0 mWC. 1.6 mW          D. 5.6 mW

Unpolarized light with intensity 200 W/m^2 travelling to the right, is incident on the left-most polarizer and goes through all three polarizers of the figure. The dotted lines are the axes of polarization of each polarizer a) What is the intensity of light leaving the left-most polarizer? b) If the middle polarizer has an axis of polarization θ2 = 75º clockwise from the vertical (viewed in the direction the light is travelling), what is the intensity of light leaving the middle polarizer? c) If the right-most polarizer has an axis of polarization θ1 = 25º counterclockwise from the vertical (viewed in the direction the light is travelling), what is the intensity of light leaving the right-most polarizer?
