In a biprism experiment, the distance between two coherent sources is 0.5 mm and that between the slit and the eyepiece is 1.2 m. The slit is illuminated by red light of wavelength 6550 Å. If red light is replaced by green light of wavelength 5240 Å , it is found that nth red bright band coincides with (n + 1)th green bright band. Calculate the distance of this band from the central bright band.
