The critical angle for an air-glass interface is
25.3°. When a light ray in air is incident on the interface, the
reflected ray is 100% polarized. What is the angle of refraction of
that ray?
Light is incident upon air-water interface (n=1.33). Calculate
the Brewster and critical angles for both internal and external
reflections. In each case, distinguish between polarization modes.
Calculate the reflectance and transmittance of water (as seen from
air) for both TE and TM polarizations with the angles of incidence
are 0, 45 and 90 degrees. Explain your findings. Calculate the
reflectance and transmittance of air(as seen from water for both TE
and TM polarizations with the angles of incidence are 0,...

percent of drivers who always buckle up before riding in a car.
They randomly survey 405 drivers and find that 299 claim to always
