All About Waves

So here is a little review about waves...



Wave Height: vertical distance between any crest and succeeding trough
Wave Length: horizontal distance between two successive crests or troughs
Crest: highest point of the wave
Trough: lowest point of the wave
Period: the time it takes two successive crests to pass a fixed point (about 6-16 seconds)
Fetch: the span of open water in which the wind blows

The size of a wave depends on:
  1. Fetch
  2. Speed of wind
  3. Length of time wind blows for

hope this helps...
