Diffraction of light-Wave Optics

Question

Orange light of wavelength $6000 \times 10^{- 10}$ m illuminates a single slit of width $0.6 \times 10^{- 4} m$ . The maximum possible number of diffraction minima produced on both sides of the central maximum is

Moderate

Solution

$\begin{array}{l} For minima dsin θ = n λ \\ \Rightarrow \sin θ = \frac{n λ}{d} < 1 \\ \Rightarrow n < \frac{d}{λ} = \frac{0.6 \times 10^{- 4}}{6000 \times 10^{- 10}} = 100 \\ T h e 100^{t h} m i n i m a c o r r e s p o n d s t o i n f i n i t y . \\ S o, o n t h e s c r e e n 99 m i n i m a o n o n e s i d e i s o b t a i n e d \\ a n d 198 o n b o t h s i d e s . \end{array}$
