  1. Q36.4 Coherent light passing through six (6) slits separated by a distance d produces a pattern of dark and bright areas on a distant screen. There will be a dark area on the screen at a position where the path difference to the screen from adjacent slits is π/2. π/3. C. π/6. D. any of these.

  2. A36.4 Coherent light passing through six (6) slits separated by a distance d produces a pattern of dark and bright areas on a distant screen. There will be a dark area on the screen at a position where the path difference to the screen from adjacent slits is π/2. π/3. C. π/6. D. any of these. A minimum occurs for phase difference that is a multiple of 2π/N

  3. Q36.5 In an x-ray diffraction experiment using a crystal, a pattern of bright spots is formed by A. interference of x-rays scattered by different atoms in the crystal. B. interference of x-rays emitted by different atoms in the crystal. C. interference of x-rays scattered by different parts of an individual atom in the crystal. D. interference of x-rays emitted by different parts of an individual atom in the crystal.
