2. In Young's double slit experiment, the positions of the bright and dark fringes depend on the distance between the slits (d), the distance from the slits to the screen (L), and the wavelength of the light (.). A. Sketch the experiment labeling L, d, and y1. B. How far do the slits need to be from the screen for the first dark fringe to be at y = 1.7 cm if the slits are 0.023 mm apart and the wavelength is 560 nm? C. Using the same slits and the distance found in part B, where would the 4th bright fringe be for 70 nm light source? 2.
