In biprism experiment the distance between 4th and 13th bright fringes on same side is measured when light of wavelength `6000 overset (@)(A)` is used.On replacing the source of light by another of different wavelength without disturbing the adjustment of the apparatus, it is found that the distance between the 5th and 15th bright fringe on same side is the same as distance measured before. What is the wavelength of light used?
