In Young's double slit experiment, light of wavelength 6000 A⁰ is used to produced fringes of width 0.8 mm at a distance of 2.5 m. If the whole appart is dropped in liquid of refractive index 1.6, then the fringe width will be

0.2mm

0.4mm

0.5mm

0.6mm

Solution

0.5mm

The Young's double slit experiment belongs to a general class of "double path "experiments, in which a wave is split into two separate waves that later combine into a single wave.

$In water λ is reduced to \frac{λ}{μ} so λ^{'} so λ^{'} = \frac{λ}{16} As ω = \frac{Dλ}{d} \propto λ \frac{ω^{'}}{ω} = \frac{λ^{'}}{λ} = \frac{\frac{λ}{16}}{λ} o r ω^{'} = \frac{0.8}{1.6} = 0.5 m m$
