In Young's double slit experiment the fringe width is `4mm` .If the experiment is shifted to water of refractive index `4/3` the fringe width becomes (in mm)

In a Young's double slit experiment, the fringe width is found to be 0.4mm . If the whole apparatus is immersed in water of refractive index 4//3 without disturbing the geometrical arrangement, the new fringe width will be

In a Young's double-slit experment, the fringe width is beta . If the entire arrangement is now placed inside a liquid of refractive index mu , the fringe width will become
