The width of central maximum of a diffraction pattern on a single slit does not depend upon
The width of central maximum of a diffraction pattern on a single slit does not depend upon
frequency of light used
width of the slit
distance between slit and source
none of these
Solution
The width of central maximum is given by $\mathrm{W}=\frac{2 \lambda \mathrm{D}}{\mathrm{a}}$
$\mathrm{W}$ depends on wavelength of light $\lambda$, which is related to the frequency.
