Make waves with a dripping faucet, audio speaker, or laser! Add a second source or a pair of slits to create an interference pattern.

Wave Interference is an easy to use, Java based simulation application designed to 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.

The sample learning goals are:
· Find points of constructive and destructive interference by eye, and by using the detectors
· Predict wave patterns created by using slits.
· Predict the pattern of a reflected wave
· Relate two dimensional representations of waves to three dimensional waves
· Explain wave patterns from interfering waves using different sources and spacing
· Recognize the Doppler effect and predict the change in frequency that occurs
· 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.

Sample Learning Goals
You can watch water, sound, and light waves move and see how they are related. All can be represented by a sinewave.
What does this sinewave represent for these three different phenomena?
Use multiple sources with different spacing and see a changing interference 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?
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.
