An iron ball has a diameter of 12cm and is 0.02 cm too large to pass through a hole in a brass plate when the ball and plate are at the same temperature of 25°C. At what temperature the same for both ball and plate would the ball just pass through the hole. (linear expansivties for iron and brass are 1.32×10^-5 K ^-1 and 2.0×10^-5 K^-1

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?
