In diffraction experiment, from a single slit, the angular width of the central maxima does NoT depend upon

In diffraction experiment, from a single slit, the angular width of the central maxima does NoT depend upon
  1. wavelength of light used
  2. distance of the slit from the screen
  3. width of the slit
  4. ratio of wavelength and slit width

Solution

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