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.
नमुना शैक्षणिक उद्दिष्ट्ये
- 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(θ) = mλ. Use the tape measure to verify your predictions.
