Amichelson interferometer operating at a 500 nm wavelength has a 3.73-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?
