**Computer animations, simulations, and applets:**

- Loaded string
- Fourier Series
- Traveling waves / standing waves (Wikipedia)
- Fourier Transform of a top-hat function (youtube)
- Audio
Spectrogram

- Dispersion
- Wikipedia entry on dispersion relation. Take a look at the animations near the bottom of the page.
- Dispersion applet.
- Youtube video of dispersion in water waves. Notice that the phase velocity is larger than the group velocity in the boat's wake.
- Anomalous dispersion in a quantum mechanical wave packet.

**David Morin's Waves and Oscillations:**- These lecture notes are well written and beautifully typeset. The content matches our course material rather well, so I encourage you to make use of them.

**Exams:**- The final exam will be held on
**Monday December 16th, from 1:30 pm to 3:30 pm in PHYS 1410.** - The final exam will be comprehensive, covering material from
the entire course.

- You will be given formula sheets, including this one, and this one, and this one.

- Hints for studying for the exam:
- Review the homeworks, the lecture notes posted below, and your own in-class notes.
- Review the Morin lecture notes posted above.
- Do any optional homework problems that you have not yet done.
- Do additional homework problems from the two recommended textbooks.
- Review the formula sheets. Make sure you understand the meaning of all the formulas that we have covered so far.
