Physics - Wave Optics Question with Solution | TestHub

Light of wavelength $6000 \times {10}^{–10} \mathrm{m}$ passes through a single slit of width $0.6 \times {10}^{–4} \mathrm{m}$. Find height of highest order of minima on both side central maxima

for minima 

$dsin\mathrm{\theta }=\mathrm{n\lambda }$

$\mathrm{sin\theta }=\frac{\mathrm{n\lambda }}{\mathrm{d}}<1$

$\mathrm{n}\le \frac{\mathrm{d}}{\mathrm{\lambda }}$

$\mathrm{n}<\frac{0.6\times {10}^{-4}}{6000\times {10}^{-10}}$

$\mathrm{n}<100$

The total number of maxima of both side at central maxima $=100+100=200$
