- BOARDWORK! A fish-finder uses sound waves to locate fish under the water. Sound travels at 1530 m/s in water. If a signal returns to the boat 1.5 s after it was sent, how deep are the fish?
- Fish-finders typically have a frequency of around 100 KHz. What is the wavelength of the signal?

- Know what the frequency and period of a wave is, and how to calculate them.
- Be able to calculate the speed of a wave.
- Understand and describe constructive and destructive interference.
- Understand and describe the parts of a standing wave.
