4. Transverse Waves: Moves at right angles to the direction of the waves energy Matter moves up and down, while energy moves side to side Demo: MATTER ENERGY
5. Longitudinal Waves a.k.a. compressional waves Medium moves in the same direction as the energy of the wave Energy and the matter move side to side Demo: MATTER ENERGY
6. CREST – high point on wave WAVELENGTH – distance on a wave from one point to the next identical point AMPLITUDE - height of wave, directly related to energy TROUGH – low point on a wave
7. WAVELENGTH – distance on a wave from one point to the next identical point (from one compression to another) COMPRESSION RAREFRACTION
8. Reflection: Bouncing back of wave Law of Reflection, the angle at which the wave hits will be the same angle at which it reflects
10. Wave Interference: Two or more waves coming in contact with another Constructive interference produces larger amplitudes Destructive interference produces smaller amplitudes
11. Ocean Wave Creation: Winds cause the formation of waves The faster and longer the wind, the larger the wave Size also depends on the fetch, the span of water over which the wind blows Larger waves Smaller waves Fetch Fetch wind
12. Ocean Wave Movement: Matter moves in a circular pattern as energy passes through
13. Types of Ocean Waves: Seas – choppy water due to storm winds resulting in peaked waves with flat troughs Swells – once away from winds crests and troughs smooth out into typical waves Breaks/Surf – in shallow water, waves slow and pile up and become higher and steeper, eventually falling over
