The thickness of an aluminum foil is measured using a Michelson interferometer that has its movable mirror mounted on a micrometer. There is a difference of 27 fringes in the observed interference pattern when the micrometer clamps down on the foil compared to when the micrometer is empty. Calculate the thickness of the foil?
How far apart must two objects be on the moon to be distinguishable by eye if only the diffraction effects of the eye’s pupil limit the resolution? Assume 550 nm for the wavelength of light, the pupil diameter 5.0 mm, and 400,000 km for the distance to the moon.
A telescope can be used to enlarge the diameter of a laser beam and limit diffraction spreading. The laser beam is sent through the telescope in opposite the normal direction and can then be projected onto a satellite or the moon. (a) If this is done with the Mount Wilson telescope, producing a 2.54-m-diameter beam of 633-nm light, what is the minimum angular spread of the beam? (b) Neglecting atmospheric effects, what is the size of the spot this beam would make on the moon, assuming a lunar distance of 3.84108 m?

Michelson's interferometer played an important role in improving our understanding of light, and it has many practical uses today. For example, it may be used to measure distances precisely. Suppose the mirror labeled 1 in the figure below is movable. If the laser light has a wavelength of 654.0 nm, how many fringes will pass across the detector if mirror 1 is moved just 1.960 (mm)? If you can easily detect the passage of just one fringe, how accurately can you measure the displacement of the mirror(nm)?

In experiments with his interferometer, Michelson found that the red cadmium line at λ=643.8nm produced fringes until one of the arms of the interferometer was moved 25cm from initially being at the coincidence or equal path length position. a. How many fringes moved through the field of view? b. What is the approximate coherence time of the light?
Condition for achieving a bright point in the Michelson's interferometer experiment is that the path difference between the two interfering beams should be Group of answer choices at least three time of ?λ , the wavelength of light used. odd multiple of ?λ /2, ?λ being the wavelength of light used. equal to the thickness of the beam-splitter glass plate. even multiple of ?λ /2, ?λ being the wavelength of light used.
