5 Light of wavelength is incident on a slit First minima of the diffraction pattern is found to lie at a distance of 6 mm from the central maximum on a screen placed at a distance of 2 m from the slit If slit width is 0 2 mm then wavelength of the light used will be a 4000 A b 6000 A c 7000 A d 7400 A
