Polarizers 1 and 3 have their axes of polarization indicated by the black solid lines, perpendicular to each other. polarizer 2 has an axis of polarization that has an angle of θ = 50.9° with respect to the polarization axis of polarizer 1. what percentage of the initial (unpolarized) light intensity passes through?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
