Problem 22.65 Constants I Periodic Table Part A A Michelson interferometer operating at a 600 nm wavelength has a 3.92-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 patten. 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...
