- 5. A very fine wire 5.5x103 mm in diameter is placed between two flat glass plates. Light whose wavelength in air is 550 nm falls (and is viewed) perpendicular to the plates and a series of bright and dark bands. (a) How many light and dark bands will there be in this case? (b) Will the area next to the wire be bright or dark? A DVF E O BA micrometer is connected to the movable mirror of an interferometer. When the micrometer is tightened down on a thin metal foil, the net number of bright fringes that move, compared to closing the empty micrometer, is 296. What is the thickness of the foil? The wavelength of light used is 589 nm.(a) What is the dimension of an area moment of inertia?(b) If the thickness of a piezoelectric cantilever beam increases, does the natural frequencyincrease or decrease?(c) Both the thickness and width of a piezoelectric cantilever beam can change the natural frequency. Which parameter (thickness or width) will lead to the natural frequency change more significantly? Briefly explain your answer.
