Question:

In a Young double slit experiment, if one of the slit is covered with a black paper then:

Options:

Fringe width of central maxima decreases

Intensity of the central maxima increases

Width of maxima decreases

Diffraction pattern is observed on the screen

Correct Answer:

Diffraction pattern is observed on the screen

Explanation:

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.
