Light of wavelength $6000 \times {10}^{– 10}m$ passes through a single slit of width $0 . 6 \times {10}^{– 4}m$. Find height of highest order of minima on both side central maxima

for minima

$dsin \theta = n \lambda$

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

$n \le \dfrac{d}{\lambda}$

$n < \dfrac{0 . 6 \times {10}^{- 4}}{6000 \times {10}^{- 10}}$

$n < 100$

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