waves (version deux)

The document discusses different types of waves including transverse waves, where the displacement is perpendicular to the wave motion, and longitudinal waves, where the displacement is parallel. It defines key wave properties like amplitude, wavelength, frequency, and speed. Constructive and destructive interference are explained. Tsunamis can be caused by earthquakes, volcanoes, and landslides. Review questions test understanding of these concepts.

- 2. Transverse Waves displacement perpendicular to wave motion
- 3. Longitudinal Waves displacement parallel to wave motion
- 4. Parts of a wave trough crest
- 5. Constructive Interference When crests and troughs combine, amplitude increases=bigger waves
- 6. Destructive Interference When crests and troughs meet, they cancel each other out=smaller waves
- 7. Speed of a Wave Velocity -speed at which the wave is traveling Frequency -number of times a wave passes a point per second Wavelength -Length of wave from crest to crest or trough to trough Velocity = Frequency x Wavelength
- 11. Tsunamis are caused by: 1-Earthquakes 3-LANDSLIDES 2-VOLCANOES
