1. Properties of Waves

2. Review
Rest Position

3. Amplitude
The maximum distance the wave vibrates from the rest position
Measured from the rest position to the crest or trough
Large amplitude = tall wave = more energy

4. Which wave has the most energy?

5. What unit would you use to measure amplitude?

6. Wavelength
The distance between any two adjacent crests or compressions in a series of waves
Always equal

7. What unit would you use to measure wavelength?

8. Frequency The number of waves produced in a given amount of time
Measured by counting the number of crests or troughs
SI unit = Hertz (Hz) = 1 wave per second

9. Frequency
Higher frequency = shorter wavelength = more energy
