Waves

1. Properties

   • Crest: The very top of the wave. Trough:The hollow between two crests wave.Height: The vertical distance between the top of one wave crest and the bottom of the next trough. Wavelength: The horizontal distance between any one point on one wave and the corresponding point on the next wave. Steepness: The ratio of height to length. Amplitude:The maximum vertical displacement of the sea surface from still water level. Period: The time it takes for one complete wavelength to pass a stationary point. Wave speed: The velocity with which waves travel.

2. Effects
