A broad source of light of wavelength 600.0 nm illuminates, at normal incidence, two glass plates 132.0 mm long that touch at one end and are separated by a wire 42.0 microns in diameter at the other end. How many bright fringes appear over the 132.0 mm distance?
6. [15 ptsJTwo glass plates are 15.0 cm long. At one end they are in contact, at the other end they are separated by 0.03 mm. Assume normal incidence with a monochromatic light (wavelength in air is 50nm) a) Is the fringe at the line of contact bright or dark? Explain your answer. What is the spacing of the bright b) If the glass plates have n 1.6 and space between plates contains water (n 1.33). Is the fringe at...
A very fine wire 7.65×10?3 mm in diameter is placed between two flat glass plates. Light whose wavelength in air is 660 nm falls (and is viewed) perpendicular to the plates and a series of bright and dark bands is seen. Part A How far apart are the dark fringes if the glass plates are each 21.5 cm long? Express your answer to three significant figures and include the appropriate units. ?x =____ (units?)
Thin film examples Suppose the two glass plates in the figure are two microscope slides 10 cm long. They are in contact at one end and are separated by a piece of paper 0.020 mm thick at the other end. What is the spacing of the interference fringes seen by reflection? Is the fringe at the line of contact bright or dark? Assume monochromatic light with λ-500 nm. λο 500 nm h - 0.020 mm 1 10.0 cm
