A Youngs double slit experiment is immersed in a liquid of refractive index The slit plane touches the liquid surface A parallel beam of monochromatic light of wavelength with respect to air is incident normally on the slits Choose the correct statement s of the following screen d 21 1 cos Liquid S JAYA YEVA A The fringe width is B If one of the slits S is covered by a transparent slab of refractive index and thickness t the new position of the central maximum will shift up by 2 1 tD d C The ratio of the intensities at O in the conditions of the option A and option B is 17 1 D If a slab of thickness t and refractive index 3 is introduced in front of S and S is also covered by a slab of thickness t and refractive index as shown in the figure then for relation 1 the central maxima will be at O
