A beam of light having wavelength $5400 \overset{˚}{A}$ from a distance source falls on a single slit $0.96 mm$ wide and the resultant diffraction pattern is observed on a screen $2 m$ away. What is the distance between the first dark fringe on either side of central bright fringe?

Options:

Answer:

Solution:

$λ = 5.4 \times 1 0^{- 7} m, D = 2 m and a = 0.96 \times 1 0^{- 3} m$ Distance between the dark fringes on either side of the central bright fringe $= \frac{2 λ D}{a} = 2.4 mm$
