Ocean 100 Lab Practical 2 Study guide Wave crest - answerTop Wave Trough - answerBottom Wavelength - answeris the horizontal distance between two adjacent crests (or two adjacent crests (or two adjacent troughs) Wave Height - answeris the vertical distance between the crest (top) and trough (bottom) Wave speed - answerindicates how fast a wave is moving across the water Period (T) - answeris the time necessary for two adjacent crests (or two adjacent troughs) to pass a specific location Frequency (F) - answeris the inverse of period (1/T) Deep Water Waves - answerWater depth greater than 1/2 of their wavelength Shallow Water waves - answerWater depth less than 1/20 of their wavelength (wave drags on bottom of the sea) Wave refraction - answeroccurs when one segment of a shallow wave encounters shallower depths than other segments of the wave Reflection - answeris the process by which a wave is returned seaward with little loss of wave energy How does friction affect wave speed? - answer- As shallow water waves approach the shore, they produce higher crests, decreasing wavelengths, and slower speeds. Breakwater - answera barrier built into a body of water to protect a coast or harbor from the force of waves Three types of tidal regimes - answer1. Diurnal- One high and one low per day (Gulf Of Mexico) 2. Semidiurnal- two nearly-equal highs and two nearly- equal lows per day (US east Coast) 3. Mixed Semidiurnal- two unequal lows per day (US West Coast) What are the two types of tides? - answer- High tide (crest of the rotating tidal wave)
