(1A) Light of wavelength 534.0 nm illuminates a double slit, andthe interference pattern is observed on a screen. At the positionof the m = 82.0 bright fringe, how much farther is it to the moredistant slit than to the nearer slit?

(1B) Light from a sodium lamp of wavelength 446.0 nmilluminates two narrow slits. The fringe spacing on a screen 137.8cm behind the slits is 6.21 mm. What is the spacing between the twoslits?

(1C) Light is incident normal to the surface of a 1.07 cmlayer of water that lies on top of a flat Lucite plate with athickness of 0.560 cm. How much more time is required for light topass through this double layer than is required to traverse thesame distance in air? (nLucite = 1.61, nwater = 1.333)
