A beam of initially unpolarized light of intensity 777 W/m^2 passes through a series of polarizing filters, each one s axis aligned at a 14.6-degree angle with respect to the previous filter s axis. The beam of light emerging from the final filter in the series has an intensity of 135.9 W/m^2. How many polarizing filters did the beam pass through?       9     34     26     17

Light is incident from air onto glass of refractive index nG=1.65 ; calculate the Brewster angle, at which the reflectance for TM polarisation is zero. Give your answer in degrees, to the nearest 0.1 degree.

If a light beam of intensity I0 that is linearly polarized along the +z-axis is incident on P1, what is the intensity of the transmitted light after it passes through all the polarizers?

Problem 1: You want to test a special watertight monochromatic light source in an un- derwater environment. If the light source shines its beam of electromagnetic radiation into your eyes when you and the light source are above the water, with both your eyes and the light source immersed in air, the beam appears to your eyes to have a deep violet color. The index of refraction of water is about 1.33 What color, if any, would your eyes perceive the beam to have when you and the light source are submerged in water – and why? (A) No color. The beam would become invisible under water because its wavelength in water is shorter than in air, corresponding to a wavelength of ultra-violet light. The beam's wavelength in the water determines its visibility to the eye under water, and ultra-violet light is not visible to the human eye. (B) Same color as in air, above the water, i.e., deep violet. Under water, the beam would have the same wavelength as in air. The beam's wavelength in the water…

A system of three polarizing sheets is placed in the path of initially unpolarized light. The polarizing direction of the first sheet, P1, is parallel to the y-axis, that of the second sheet, P2, is 60o counterclockwise from the y-axis, and that of the third sheet, P3, is parallel to the x-axis. Determine the fraction of the initial intensity Io of the light emerges from the system, i.e. ratio I0/I3.     A.    0.092     B.    3.19     C.    10.9     D.    6.66

A beam of unpolarized light of intensity 2.17E3 W/m2 passes through a series of ideal polarizing filters with their polarizing directions turned to various angles as shown in the figure.  What is the light intensity at point C (in W/m2)? Use 3 sig figs and scientific notation

A thin sheet of material of refractive index n = 1.2 (relative to air) is illuminated with a flat wave of monochromatic light. It is observed that for a reduced set of angles of incidence on this sheet (relative to the normal one) there are maximum reflections. Measurements were taken that determined the values ​​of two consecutive angles, for which the maximum reflection occurs: θa = 62.75∘ and θb = 43.25∘. What is the thickness of this lamina, in nm, given that the wavelength of the incident light is λ = 460 nm?
