Description

Make waves with a dripping faucet, audio speaker, or laser! Add a second source to create an interference pattern. Put up a barrier to explore single-slit diffraction and double-slit interference.

Sample Learning Goals

  • Make waves with water, sound, and light and see how they are related.
  • Design an experiment to measure the speed of the wave.
  • Create an interference pattern with two sources, and determine the ways to change the pattern.
  • Find points of constructive and destructive interference by eye, and by using the detectors.
  • Put up a barrier to see how the waves move through one or two slits. What sort of pattern do the slits create? How can you change this pattern?
  • For light, predict the locations of the fringes that appear on the screen using d sin(θ) = mλ. Use the tape measure to verify your predictions.
