In Young’s double slit experiment, the aperture screen distance is $2m$. The fringe width is $1\ mm$. Light of $600\ nm$ is used. If a thin plate of glass $(\mu = 1.5)$ of thickness $0.06\ mm$ is placed over one of the slits, then there will be a lateral displacement of the fringes by

(b) Lateral displacement of fringes $= \frac{\beta}{\lambda}(\mu - 1)t$
$= \frac{1 	imes 10^{- 3}}{600 	imes 10^{- 9}}(1.5 - 1) 	imes 0.06 	imes 10^{- 3} = 5\ cm$
