At t=0 , the slab starts to move down with constant acceleration `a_0` Thus the fringe patten starts to shift . After some time , the patten again becomes static . What time instant is this ? (The distance between the slits is 'd' and `theta` is very small. )

A

`sqrt(d//a)`

B

`2sqrt(d//a)`

C

`sqrt(2d//a)`
