Light of wavelength 6000 overset(@)A is ...

Light of wavelength 6000 `overset(@)A` is used to obtain interference fringe of width 6 mm in a young's double slit experiment. Calculate the wavelength of light required to obtain fringe of width 4 mm if the distance between the screen and slits is reduced to half of its initial value.
