Two slits in Young's double slit experiment are 1.5 mm apart and the screen is placed at a distance of 1 m from the slits. If the wavelength of light used is $600 \times 1 0^{- 9} m$ then the fringe separation isNEET 2024 (Re-NEET)

Options:

Answer:

Solution:

Fringe width $=$ Fringe separation $(β) = \frac{λ D}{d}$ $\Rightarrow β = \frac{600 \times 1 0 ^{- 9} \times 1}{1.5 \times 1 0 ^{- 3}} = \frac{6 \times 1 0 ^{- 7}}{1.5 \times 1 0 ^{- 3}} = 4 \times 1 0^{- 4} m$
