Wave Interference make waves with a dripping faucet, audio speaker, or laser. You can add a second source or a pair of slits to create an interference pattern.

Sample Learning Goals:
1. You can watch water, sound, and light waves move and see how they are related. All can be represented by a sinewave.
2. What does this sinewave represent for these three different phenomena?
3. Use multiple sources with different spacing and see a changing interference pattern.
4. Find points of constructive and destructive interference by eye, and by using the detectors.
5. 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?
6. In the light panel, predict the locations of the fringes that appear on the screen using d sin(?) = m?. Use the tape measure to verify your predictions.
