How does a degree on the Fahrenheit scale compare with a degree on the Celsius scale? Remember to use the calibration
points on each scale in your comparison. Can you think of a
way to change the temperature from one scale to the other?

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?
