cisce.org(v) In Young’s double slit experiment, what is the effect on fringe pattern if the slits are brought closer to each other? [1] (a) Fringes disappear. (b) Fringe width increases. (c) Fringe width decreases. (d) Fringe width remains unaltered. (vi) First line of Balmer series (Hα) in the spectrum of hydrogen is obtained when an

web.mit.edu14.2 Young’s Double-Slit Experiment In 1801 Thomas Young carried out an experiment in which the wave nature of light was demonstrated. The schematic diagram of the double-slit experiment is shown in Figure 14.2.1. Figure 14.2.1 Young’s double-slit experiment. A monochromatic light source is incident on the first screen which contains a slit .
