Part A One Round Face Of A 3 50 M Solid Cylindrical Plastic Pipe Is Covered With A Thin Black Coating That Completely 1 (28.66 KiB) Viewed 34 times

Part A One round face of a 3.50 m, solid, cylindrical plastic pipe is covered with a thin black coating that completely blocks light. The opposite face is covered with a fluorescent coating that glows when it is struck by light. Two straight, thin, parallel scratches, 0.210 mm apart, are made in the center of the black face. When laser light of wavelength 632.8 nm shines through the slits perpendicular to the black face you find that the central bright fringe on the opposite face is 5.62 mm wide, measured between the dark fringes that border it on either side. What is the index of refraction of the plastic? Express your answer numerically. ΙΙ ΑΣφ ? n = Submit Request Answer Provide Feedback
