Q. In Young’s double slit experiment, a mica slit of thickness $t$ and refractive index $\mu$ is introduced in the ray from the first source $S_{1}$. By how much distance the fringes pattern will be displaced
A) $\frac{d}{D}(\mu - 1)t$
B) $\frac{D}{d}(\mu - 1)t$
C) $\frac{d}{(\mu - 1)D}$
D) $\frac{D}{d}(\mu - 1)$
