Two statements about interference of light from two narrow slits, lit by the same coherent monochromatic source, are given below. Statement I: With the screen where it is, moving the two slits closer together makes the fringes on the screen narrower. Statement II: At the dark fringes the energy of the two waves is destroyed, so the total energy reaching the screen is less than the sum of the two separate beams. New
