Q: What is the correct answer for CUET UG Physics Q24?

The correct answer is d. Young's Double Slit Experiment (YDSE) produces an interference pattern on the screen due to the superposition of coherent light waves from two slits. If one of the slits is covered with black paper, the setup effectively transforms into a single-slit experiment. A single slit, when illuminated by light, produces a diffraction pattern, not an interference pattern. This diffraction pattern consists

Q24. In a Young double slit experiment, if one of the slits is covered with a black paper then:
(a) Fringe width of central maxima decreases
(b) Intensity of the central maxima increases
(c) Width of maxima decreases
(d) Diffraction pattern is observed on the screen

FirstInTest · Accepted Answer

Young's Double Slit Experiment (YDSE) produces an interference pattern on the screen due to the superposition of coherent light waves from two slits. If one of the slits is covered with black paper, the setup effectively transforms into a single-slit experiment. A single slit, when illuminated by light, produces a diffraction pattern, not an interference pattern. This diffraction pattern consists of a broad central maximum and progressively narrower, less intense secondary maxima and minima. Therefore, the characteristic interference fringes disappear, and a single-slit diffraction pattern is observed instead. Options (a), (b), and (c) describe changes to an interference pattern, which would no longer be the dominant phenomenon.

Answer

Fringe width of central maxima decreases

Answer

Intensity of the central maxima increases

Answer

Width of maxima decreases

Answer

Diffraction pattern is observed on the screen
