The period of a simple pendulum, defined as the time necessary for one complete oscillation, is measured in time units and is given by
g
T  2 l
where , l is the length of the pendulum and g is the acceleration due to gravity, in units of
length divided by time squared. Show that this equation is dimensionally consistent

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?
