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

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 :

In young's double-slit experiment, both the slits produce equal intensities on a screen. A 100% transparent thin film of refractive index mu = 1.5 is kept in front of one of the slits, due to which the intensity at the point O on the screen becomes 75% of its initial value. If the wavelength of monochromatic light is 720 nm, then what is the minimum thickness (in nm) of the film?
