In a biprism experiment to determine the wavelength of light the distance between the slit and the eyepiece is 1 m. Wavelength of light used is 5600 A.U. When a convex lens is kept at a distance of 30 cm from the slit, the distance between the two images is 0.7 mm. Find (1) band width (2) the distance of the 4th dark band from the central bright band.
