An evacuated cell of length 10 cm is placed in one arm of a Michelson interferometer using a 589-nm light source. When methane gas is allowed to enter the cell, the interference pattern is observed to shift 75 fringes as the pressure increases to atmospheric value. Calculate the index of refraction of methane. If we remove the evacuated cell then, a shift of 50 fringes will correspond to displacing the movable mirror of the interferometer by what distance?

In one arm of a Michelson interferometer, a flame is placed below one of the arms which heats the air and changes its index of refraction. As the air heats up, 5 interference fringes (m = 5) are observed while using a laser of wavelength 650 nm. If the index of refraction of room temperature air is 1.00029, what is the index of refraction of hot air? Assume the flame diameter is 3 mm.

A Michelson interferometer operating at a 400 nmwavelength has a 2.31-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.

An important experimental device that uses interference is the Michelson interferometer. Michelson interferometers are used to make precise measurements of wavelengths and of very small distances. A Michelson interferometer takes monochromatic light from a single source and divides it into two waves that follow different paths. Interference occurs when the two light waves are recombined. The figure below shows the principal components of a Michelson interferometer. A ray of light from a monochromatic source A strikes the beam splitter C,...
