A person riding in a boat observes that the sunlight reflected by the water is polarized parallel to the surface of the water. The person is wearing polarized sunglasses with the polarization axis vertical. If the wearer leans at an angle of 22.0 ∘ to the vertical, what fraction of the reflected light intensity will pass through the sunglasses?

One goal of the Russian space program is to illuminate dark northern cities with sunlight reflected to the Earth from a 200 m diameter mirrored surface in orbit. Several smaller prototypes have already been constructed and put into orbit. (a) Assume that sunlight with intensity 1340 W/m2 falls on the mirror nearly perpendicularly and that the atmosphere of the Earth allows 78.3% of the energy of sunlight to pass though it in clear weather. What is the power received by...

A beam of unpolarized sunlight strikes the vertical plastic wall of a water tank at an unknown angle. Some of the light reflects from the wall and enters the water. The refractive index of the plastic wall is 1.61. If the light that has been reflected from the wall into the water is observed to be completely polarized, what angle does this beam make with the normal inside the water?

Project (2) Read the manual When unpolarized light is incident on the surface of (say) glass at the Brewster angle, the reflected light is polarized with its polarization parallel to the surface of the glass. The Brewster angle is given by Tan(O) = n where n is the refractive index of glass. The material need not be glass; it could be plastic, water etc. (any smooth transparent material is fine).
