Two components of an interferometer are a moveable mirror and a beam splitter. Which of the following are NOT true statements regarding each component in creating an interferogram?
I. When the mirror travels a distance of λ/4, deconstructive interference occurs.
II. The beam splitter alternates the incident light between a reference and the sample.
III. When the mirror travels a distance of λ/2, deconstructive interference occurs.
IV. The beam splitter splits the incident light between the stationary mirror and the moveable mirror.

In a Michelson interferometer, a laser beam is split into two beams as shown in the figure.
When the two beams are combined, an interference pattern is seen on the observation
screen. The interference pattern is a series of concentric bright circles separated by dark
ones as shown in the figure. At the center of the pattern is a bright circular spot. Suppose
the movable mirror is slowly moved toward the beam splitter by distance 1/2. As this is
done, what happens to the interference pattern? a) There is no change in the interference
pattern. b) The interference pattern becomes brighter, but otherwise remains the same.
c) The central bright spot turns into a dark spot (B → D). d) The central bright spot turns
into a dark spot and then back into a bright spot (B → D → B). e) The central bright spot
turns into a dark spot, then into a bright spot, and then back into a dark spot (B → D →
B → D).

The Michelson interferometer can be used to measure the index of refraction of a gas by placing an evacuated transparent tube in the light path along one arm of the device. Fringe shifts occur as the
gas is slowly added to the tube. Assume 580-nm light is used, the tube is 5.40 cm long, and 152 fringe shifts occur as the pressure of the gas in the tube increases to atmospheric pressure. What is
the index of refraction of the gas? Hint: The fringe shifts occur because the wavelength of the light changes inside the gas-filled tube. (Give your answer to five decimal places.)
