Two monochromatic and coherent point sources of light s, and s, of wavelength 4000 , are placed at a distance 4 mm from each other. The line joining two Sources is perpendicular to screen. The distance of midpoint of s,s, from the screen is D=J2m- Find the area (in em²) of smallest bright ring on cm2 screen.
