In single slit diffraction experiment, when the distance of separation between the slit and screen is doubled, the angular separation between fringes
  1. increases.
  2. decreases.
  3. remains same.
  4. first increases and then decreases.

Solution

Linear width of central maximum \(=\frac{2 \lambda D}{d}\) \(\therefore\) Angular width of central maximum \(=\frac{2 \lambda}{d}\)
