Light of wavelength $5000 \overset{˚}{A}$ is incident normally on a slit. The first minimum of the diffraction pattern is observed to lie at distance of $5 mm$ from the central maximum on a screen placed at a distance of $2 m$ from the slit. The width of the slit.is

Options:

Answer:

Solution:

The slit width is given as: $W = \frac{λ D}{d}$ $∴ d = \frac{2 \times 5000 \times 1 0 ^{- 10}}{5 \times 1 0 ^{- 3}} = 0.02 cm$
