Ex /18: In Young's experiment, the separation between the slits is 3 mm nad the distance between the slits and the screen is 1 m. If the wavelength of light used is 6000 A.U., calculate the fringe width. What will be the change in fringe width, if entire apparatus is immersed in a liquid of refractive index 4 3
