In a YDSE experiment, the two slits are covered with a transparent membrane of negligible thickness which allows light to pass through it but does not allow water. A glass slab of thickness t = 0.41 mm and refractive index mg = 1.5 is placed in front of one of the slits as shown in the figure. The separation between the slits is d = 0.30 mm. The entire space to the left of the slits is filled with water of refractive index mw = 4/3.

A coherent light of intensity I and absolute wavelength l = 5000A° is being incident on the slits making an angle 30° with horizontal. If screen is placed at a distance D = 1m from the slits, the position of central maxima will be
