: In a biprism experiment the slit is illuminated by a light of wavelength 4800 A.U. The distance between slit and biprism is 20 cm and the distance between biprism and eye piece is 80 cm. If the distance between virtual sources is 3 mm, determine the distance between the 5th bright band on one side of the central band and 5th dark band on other side.
