A) A screen containing two slits 0.7 mm apart is 1.3 m from the viewing screen. Light of wavelength 732 nm falls on the slits from the distance source. Approximately how far are adjacent bright fringes on the screen? Give answer in mm.

B) Light of wavelength 732 nm falls on two slits and produces an interference pattern in which the third order bright fringe is 36 mm from the central fringe on the screen 2.9 m away. What is the distace between two slits? Give answer in mm.

C) For a double-slit experiment, the third-order maximum for light of wavelength 543 nm is located 13 mm from the central bright spot on a screen some distance away from the slits. Light of wavelength 692 is then used in the same setup. How far from the central bright spot will be the second-order maximum of this light be located on the screen? Give answer in mm.

D) What is the smallest thickness of a soap film (n=1.33) surrounded by the air that would appear dark being illuminated with 589 nm light? Give answer in nm.
