In a double slit experiment, the distance of the screen fromthe slits is half a meter. The wavelength of the given source forconducting this experiment is 480 nm, slit separation is 0.12 mmand the slit width is 0.025 mm. (a) Calculate the adjacentinterfering fringe separation (b) Find the distance from thecentral maximum to the first minimum of the fringe envelope? (c)How many fringes will you find inside this envelope?
