Machines have moving parts and electronics that can overheat in some situations. Engineers use metal
heat sinks to help the heat escape from the machine. A heat sink is made of metal and usually has fins,
which give the heat sink a large surface area. Why is it important for heat sinks to be made of metal and
have a large surface area?

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?
