In a double slit experiment a monochromatic light of wavelength 500 nm is used The fringe pattern is observed on a screen 1m away on a screen Fringe width is found to 0 4mm If the entire arrangement is immersed in a liqid in which velocity of light is 1 5 x 108 ms 1 then the fringe width becomes A 0 2 mm B 0 3 mm C 0 4 mm D 0 25 mm
