WAVES

Causes Wind waves- Growth Wind waves move energy, not matter Wind-capillary/wind waves Earthquakes-Tsunamis Graviational attraction-Tides Wind waves move energy, not matter Wind waves- Growth Wind strength- must be moving faster than waves Wind duration-longer creates larger waves Fetch- uninterrupted distance

Internal waves

What affects waves? Wave refraction- As wave travels in to different depths waves bend, and change in speed: speed up or slow down Wave diffraction- Disturbance due to an obstacle- spreading out through a gap https://youtu.be/E9UJjdlTQQI

What affects waves? Wave reflection- Waves bounce back from an obstacle Wave interference- overlapping waves (either cancel each other out or grow in amplitude)

So what…?
