Описание: In young\'s double slit experiment the slits are illumated by light of wavelength `5890^(@)` A and the distance between the fringes obtained on the screen is `0.2^(@)`. If the whole apparatus is immersed in water then the angular fringe width will be, if the refractive index of water is `4//3`
