In the experiment of diffraction due to a single slit, if the slit width is decreased, the width of the central maximum

Options

  1. Abecomes zero.
  2. Bdoes not change.
  3. Cincreases.
  4. Ddecreases.

Correct answer

C. increases.

Step-by-step solution

Width of the central maxima = W = d Thus, the slit width is inversely proportional to the width-of the central maximum. Hence, when the slit width is decreased, the width of the central maxima increases.
