- Determine the amplitude coefficient of transmission for light moving perpendicularly from air-to-ice and from ice- to-air. The refractive index of ice is 1.31.Unpolarized light is sent into a system of three polarizing sheets. The angles θ1, θ2, and θ3 of the polarizing directions is measured counterclockwise from the positive direction of the y axis. Angles θ1 and θ3 are fixed, but angle θ2 can be varied. The figure gives the intensity of the light emerging from sheet 3 as a function of θ2. (a) From the intensity plot, what are the possible orientations of the first and third polarizers? Draw a sketch of the situation. (b) What percentage of the light’s initial intensity is transmitted by the three-sheet system when θ2 = 90°? Answer: 7.3%Light traveling in a medium with a refractive index 1.31 is incident on a plate of another medium with index of refraction 1.39. At what angle of incidence is the reflected light fully polarized?
- A ray of light enters a liquid from air. If the angle between the incident and refracted rays is 133° and the angle between the reflected and refracted rays is 76°, find the refractive index of the liquid. Assume the refractive index of air is 1.00.A ray of light crosses the boundary between some substance with n = 1.54 and air, going from the substance into air.
