She noticed an advertisement that let one choose the angle of polarization orientation of the sunglasses. What polarization angle, if any would you advise her to choose for her new glasses. Question 6 options: A pair of polarizing sunglasses offers no advantage for a people near the water. Sunglasses with a horizontally oriented polarizer would be best for reducing ocean glare. Sunglasses with a vertically oriented polarizer would be best for reducing ocean glare.6. In a polarizer-analyzer combination, 90.0% of the light intensity falling on the analyzer is absorbed. Determine the angle between the transmission axes of the polarizer and analyzer.

S Ex0 Eyo where 8 = 8, - 8p.** 46. How much unpolarized light gets through a polarizer? Unpolarized light is as likely to have its polarization vector in one direction as another. Therefore, on average, the up-down component of the polarization vector for unpolarized light will be the same as the right- left component. These equal components in two perpendicular directions are in the same relationship as the E-field components when polarized light hits a polarizer with its polariza- tion vector at 45° to the optic axis. We can use this connection to find out what fraction of the energy in an incident unpolarized beam makes it through the polarizer as polarized light. a) If an electric field vector of a polarized light beam is 45° to the optic axis of the polar- izer, find the ratio between the magnitude of the electric field vector that passes through the polarizer and the magnitude of an incident polarized electric field vector. This will be the same as the ratio of the magnitude of the electric field of the…2 Take a vertical polarizer and look through it. Take a second polarizer rotated at 90° (so it becomes a horizontal polarizer) and put it in front of the first one. How much light coming out of the vertical polarizer makes it through the horizontal one? Answer: 3 Are horizontal and vertical polarizations are mutually exclusive? Answer:.
