This document discusses different types of waves and their properties. It describes transverse waves, where displacement is perpendicular to motion, and longitudinal waves, where displacement is parallel. It also defines key wave properties like crests, troughs, wavelength, frequency, velocity, and discusses how constructive and destructive interference can cause waves to increase or decrease in amplitude. Tsunamis are summarized as being caused by earthquakes, volcanoes, and landslides.

- 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 ïƒ bigger waves (IN PHASE)
- 6. Destructive Interference When crests and troughs meet, they cancel each other out ïƒ smaller waves OUT OF PHASE
- 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
- 8. Tsunamis are caused by: 1-Earthquakes 3-LANDSLIDES 2-VOLCANOES
