A screen containing two slits 0.4 mm apart is 1.5 m from the viewing screen. Light of wavelength 643 nm falls on the slits from the distance source. Approximately how far are adjacent bright fringes on the screen? Give answer in mm.
Light of wavelength 643 nm falls on two slits and produces an interference pattern in which the third order bright fringe is 39 mm from the central fringe on the screen 2.6 m away. What is the distace between two slits? Give answer in mm.
For a double-slit experiment, the third-order maximum for light of wavelength 507 nm is located 16 mm from the central bright spot on a screen some distance away from the slits. Light of wavelength 653 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.
