Alaser beam enters a 20.0 cm thick glass window at an angle of 41.0° from the normal. the index of refraction of the glass is 1.49. at what angle from the normal does the beam travel through the glass? how long does it take the beam to pass through the plate?

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?
