• Jason thinks he's got a faster are than Isaac. To prove it, he hups in
his car and starts to drive. He
accelerates at a rate of 2.5
m/s2 from 27 m/s to 36 m/s. How
long does this take? Is Jason
faster? Who's acceleration is
better?

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?
