Two narrow slits are used to produce a double-slit interference pattern with monochromatic light. The slits are separated by 7 mm, and the interference pattern is projected onto a screen 7 m away from the slits. The central bright fringe is at a certain spot on the screen. Using a ruler with one end placed at the central fringe, you move along the ruler passing by two more bright fringes and find that the next bright fringe is 21.5 mm...
