How is frequency related to period? a) They are the same thing.
b) Period - 1 / frequency.
c) Frequency = amplitude x period.
d) Speed = period / frequency,
e) Period = speed x frequency.​

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?

Convection currents are caused by differences in what two things?
