Question

Ex. 56: In a biprism experiment interference
bands are abserved at a distance of 1 m from
the slit. A convex lens is put between the slit
and eyepiece gives two images of slit 0.7 cm
apart, the lens being 70 cm from eyepiece.
Calculate the width of 100 bands, if light of
wavelength 5890 A is used.
