In diffraction experiment from a single slit, the angular width of central maximum does NOT depend upon
  1. ratio of wavelength and slit width
  2. distance of the slit from the screen
  3. wavelength of light used
  4. width of the slit

Solution

Angular width of central maximum $\theta=\frac{2 \lambda}{\mathrm{a}}$ Hence, the angular width of central maximum does not depend upon distance of the slit from the screen (4).
