In biprism experiment, the slit is illuminated by red light of wavelength 6400 A.U. and crosswire is adjusted at the centre of third bright band. Without distributing the setting, red light is replaced by blue light and it is found that the centre of fourth bright band is at the intersection of the crosswire. Find the wavelength of blue light.
