Answer #1

Solution y = (261) (2h-1) do 2 d for darle dringes Da 2m d - 2.5X10-3m. G = 2.5x10-2m so) h=3 2 2-5X10? = (3-k) x + x2 2.5810

    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...
