1. A laser of unknown wavelength is aimed at a double slit in an opaque screen, with slits 0.8 mm apart. The resulting wave pattern is projected onto a screen 2.0 m beyond it. You make the following measurements relative to the central maximum: Bright Fringes: 1.1 mm, 2.2 mm, 3.4 mm, 4.5 mm Dark Fringes: 0.6 mm, 1.7 mm, 2.8 mm, 3.9 mm Given this information, find the following: a) The wavelength of your laser. b) The position of the 5th order bright fringe to the nearest one-tenth of a millimeter. c) The position of the fifth order dark fringe to the nearest one-tenth of a millimeter. Note that your position measurements are accurate to only the nearest 0.1 mm. This means your wavelength calculation from each position measurement will vary slightly from the others. How should you handle this
