Certain sunglasses use a polarizing material to reduce the intensity of light reflected as glare front water or automobile windshields. What orientation should the polarizing filters haw to be most effective? (a) The polarizers should absorb light with its electric field horizontal. (b) The polarizers should absorb light with its electric field vertical. (c) The polarizers should absorb both horizontal and vertical electric fields. (d) The polarizers should not absorb either horizontal or vertical electric fields.
Explain why the “invisible man” would be unable to see.
When light reflects off a surface, it becomes polarized, but is it polarized vertically or horizontally? We can answer this question knowing that sunglasses have a vertical transmission axis because they are designed to block this annoying surface- reflected light from entering our eyes. Based on this knowledge, what kind of polarization does reflected light have: vertical or horizontal
These are the options from the practice homework in book. I'm confused bc they're not alligning. Any insight? Thanks. -None of it. This first only lets vertically polarized light through. the second only let horizontally polarized light through. -All of it. Since the two polarizers aren't aligned with each other, they don't affect the light. -One quarter. Each polarizer reduces the light by half. Half of half is one quarter. -70.7%. The combination of the two polarizers (one at 0 and the other at 90) is 45. Cos(45)=.707.
Problem 7: Brewster plates are used in laser cavities to polarize the light with the smallest amount of power loss possible (see figure). Suppose the laser cavity is filled with air (n = 1) and the Brewster's plate is made of glass (ng = 1.44). Part (a) What is the angle the normal to the plate must make with respect to the laser beam, θB, if the polarization of the reflected light is maximized? Answer in radians. Part (b) If instead this were a dye laser, whose cavity is filled with a liquid solution with ns = 1.3. What is the angle, θB, in radians?

Brewster plates are used in laser cavities to polarize the light with the smallest amount of power loss possible (see figure). Suppose the laser cavity is filled with air (n = 1) and the Brewster's plate is made of glass (ng = 1.5). a) What is the angle the normal to the plate must make with respect to the laser beam, θB, if the polarization of the reflected light is maximized? Answer in radians. b) If instead this were a dye laser, whose cavity is filled with a liquid solution with ns = 1.3. What is the angle, θB, in radians?
Physics Polarization: Write down the equations of an unpolarized E field before it hits a linear polarizer that is polarized in the x-direction. What are the E field equations after the linear polarization? I'm having extreme difficulty on this problem, need some guidance.
A life-guard wants your help choosing a pair of new sun-glasses to minimize reflections from the water. 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.
Polarized light is incident on 10 polarizing sheets the access of the first polarize she makes an angle theta with the plane of polarization each subsequent Sheet has an axis that is rotated by an angle theta from that of adjacent sheets find theta if 29% of the incident intensity is transmitted by the sheets. Suppose you want to rotate the plan of polarization of a beam of a polarize light by 90° but you do not want the Final intensity to be less than 66% of the initial intensity what is the minimum number of polarizing sheets you must use? Assume that if she is rotated the same angle relative to the adjacent sheets
Polarized light is incident on 8 polarizing sheets the access of the first polarize sheet makes an angle theta with the plan of polarization each subsequent sheet has an access that is rotated by an angle theta from that of adjacent sheets find theta of 83% of the incident intensity is transmitted by the sheets Suppose you want to rotate the plane of polarization of a beam of polarized light by 73° but you do not want the Final intensity to be less than 87% of the initial intensity what is the minimum number of polarizing sheets you must use assume that each sheet is rotated by the same angle relative to the adjacent sheets
Suppose you want to rotate the plane of polarization of a beam of polarized light by 67°, but you do not want the final intensity to be less than 88% of the initial intensity.
