A double-slit experiment is performed underwater with a submergedHeNe laser. Suppose that the separation of the slits is0.0142 cm, while the wavelength of the light in air is633 nm. The screen is 2.53 m away from theslits. Find the distance along the screen, measured from thecenterline, that corresponds to the second bright fringe(m = 2). The index of refraction of water is1.33.
