A parallel beam of monochromatic light falls normally on a single narrow slit. The angular width of the central maximum in the resulting diffraction pattern

Options

  1. Aincreases with increase of slit width.
  2. Bdecreases with increase of slit width.
  3. Cdecreases with decrease of slit width.
  4. Dmay increase or decrease with decrease of slit width.

Correct answer

B. decreases with increase of slit width.

Step-by-step solution

Width of central maximum W_c=2 D a W _ e 1 a Angular width of principal maximum decreases with increase in width of the slit.
