# Orange light of wavelength $6000 \times 10^{-10}$m illuminates a single slit of width $0.64 \times 10^{-4}m$. The maximum possible number of diffraction minima produced on both the sides of the central maximum is______ Option: 1 198 Option: 2 99 Option: 3 45 Option: 4 30

\begin{aligned} &\text { Condition for minimum, }\\ &d \sin \theta=n \lambda\\ &\therefore \sin \theta=\frac{\mathrm{n} \lambda}{\mathrm{d}}<1\\ &\mathrm{n}<\frac{\mathrm{d}}{\lambda}=\frac{6 \times 10^{-5}}{6 \times 10^{-7}}=100 \end{aligned}

$\therefore \quad Total number of minima on one side = 99 \\ Total number of minima =198 \\ Correct Answer is 198$
