(4 pt) A beam of photons passes through a narrow slit. The photons land on a distant screen, forming a diffraction pattern. In order for a particular photon to land at the center of the diffraction pattern, it must pass (a) through the center of the slit. (b) through the upper half of the slit. (c) through the lower half of the slit. (d) impossible to decide 7. (4 pt each) In the Young\'s Double Slit Experiment, 2 slits are separated by d and the viewing screen is located L from the slits. Choose the correct answer. 8. The single source of monochromatic light ? starts in phase, and travel the same distance. (8.1) They will arrive at the point P on the viewing screen: _(in phasel or (out of phasel (8.2) The light waves on the screen emerging from the two slits are al Constructive Solution Solution ) it is option D As light gets refracted along different directions there will be deviation so it is not possible to decide They should be in phase It should be constructive .
