In a Young double slit experiment, if one of the slit is covered with a black paper then: |
Fringe width of central maxima decreases Intensity of the central maxima increases Width of maxima decreases Diffraction pattern is observed on the screen |
Diffraction pattern is observed on the screen |
The correct answer is Option (4) → Diffraction pattern is observed on the screen When one slit is covered, the system no longer produces an interference, but a single slit diffraction pattern from the remaining open slit will be observed. |
