CUET · PHYSICS · PYQ PAPER 2023
In a Young double slit experiment, if one of the slit 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
Answer & Solution
Correct Answer
(D) Diffraction pattern is observed on the screen
Step-by-step Solution
Detailed explanation
Interference requires two coherent light sources; when one slit is covered, light can only pass through the remaining single slit. Consequently, the interference fringes disappear and are replaced by a standard single-slit diffraction pattern. D) Diffraction pattern is observed…
