In Young's double slit experiment the two slits are d distance apart. Interference pattern is observed on a screen at a distance D from the slits. A dark fringe is observed on the screen directly opposite to one of the slits. The wavelength of light is

Options:

Answer:

Solution:

Hints:
$n^{th}$ Dark fringe $(2 n - 1) \frac{D λ}{2 d} = \frac{d}{2} λ = \frac{d ^{2}}{( 2 n - 1 ) D} = \frac{d ^{2}}{D} [for n = 1]$
