In a double slit experiment a parallel beam of light strikes the slit plane at an angle theta as shown in the figure. The two slits are covered with transparent plastic sheets of equal thickness t but of different refractive indices 1.2 and 1.5. The central maxima is formed at the centre of the screen at C.

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 :
