(A) Given: Wavelength $\lambda = 600 \,nm = 600 \times 10^{-9} \,m$. Width of the slit $a = 0.2 \,mm = 0.2 \times 10^{-3} \,m$. The angular width of the central maxima in a single-slit diffraction pattern is given by the formula $\theta = \frac{2\lambda}{a}$. Substituting the values: $\theta = \frac{2 \times 600 \times 10^{-9} \,m}{0.2 \times 10^{-3} \,m}$. $\theta = \frac{1200 \times 10^{-9}}{0.2 \times 10^{-3}} = 6000 \times 10^{-6} \,rad = 6 \times 10^{-3} \,rad$. Thus, the angular width of the central maxima is $6 \times 10^{-3} \,rad$.
