In the Young’s double slit experiment, a mica slip of thickness t and refractive index

\mu

is introduced in the ray from first source

{S_1}

. By how much distance fringes pattern will be displaced.

View answer and explanation

Correct option: B

\frac{D}{d}\left( {\mu - 1} \right)t

Option B (

\frac{D}{d}\left( {\mu - 1} \right)t

) is correct because the fringe shift is directly proportional to the thickness of the mica slip and the refractive index minus 1.
