283497 A single slit diffraction pattern is obtained on a screen using \(600 \mathrm{~nm}\) light when the width of the central (principal) maximum is \(0.30 \mathrm{~mm}\). The width of the slit is reduced by \(50 \%\) and then illuminated by \(450 \mathrm{~nm}\) light. Width, in \(\mathrm{mm}\), of the central maximum in the second case is,
