Angular width of central maximum of a diffraction pattern due to a single slit does not depend upon
Angular width of central maximum of a diffraction pattern due to a single slit does not depend upon
Distance between slit and source
Wavelength of light used
Width of the slit
Frequency of light used
Solution
Angular width of central maxima is given by, $\mathrm{Q}=2 \lambda \mathrm{a}$
Where,
$\lambda=$ Wavelength
$\mathrm{a}=$ Width of slit,
It does not depend on distance between slit and source.
