1. Review of Waves

2. Review
What is the difference between asking for “the distance between successive parts of a wave and the time between successive parts of a wave”?

3. Review
How are wave height and amplitude related?

4. Review
How are frequency and period related?

5. Name the Behavior

6. What is the magnitude of one wavelength?

7. Word Problem Practice
Two boats are anchored in the harbor, separated by a horizontal distance of 30 m. The boats bob up and down as waves enter the harbor. When one boat is at its highest point, the other is at its lowest point and there is one wave crest between them. Each boat makes exactly 2 complete up-and-down cycles every 10.0 s. The vertical distance between a boat's highest and lowest position is 3.0 m. Determine the wavelength (m), frequency (Hz), period (s), amplitude (m), and speed (m/s) of the waves.
