Question

The figure shows a Young's double slit experimental setup. It is observed that when a thin transparent sheet of thickness t and refractive index μ is put in front of one of the slits, the central maximum gets shifted by a distance equal to n fringe widths. If the wavelength of light used is λ, t will be:
(A) (2nDλ)/a(μ — 1) (B) (nDλ)/a(μ — 1)
(C) (2Dλ)/a(μ — 1) (D) (Dλ)/a(μ — 1)
