A thin transparent sheet is placed in front of a Young's double slit. The fringe width will

There is a Young's double-slit experiment set-up completely dipped in water. Assume that the refractive index of water is mu_1 . One of the slits is covered with a thin film of thickness t and refractive index mu_2 . What will be the optical path difference at the centre of screen ?

In a Young's double slit experimental arrangement shown here, if a mica sheet of thickness t and refractive indec mu is placed in front of the slit S_1 , then the path difference (S_1P-S_2P) is

In a Young's double slit experimental arrangement shown here, if a mica sheet of thickness t and refractive indec mu is placed in front of the slit S_1 , then the path difference (S_1P-S_2P) is

In a Young's double slit experiment let A and B be the two slits. A thin plate of thickness t and refractive index mu is placed in front of A. Let beta be the fringe width. The central maximum will shift

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 mu is put 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 lambda , t will be :
