because of wind
Tides
amplitude
elctro-magnetic waves
Wave speed = (wavelength)/(period)
fgyg
Wave frequency f, and period of wave T are inverses, related by fT=1.
because motion is moving and wave motion has waves
The greatest high tides are Spring tides where the Earth, Moon, and Sun are in a line. They are also the lowest low tides. The least high tides and low tides are called neap tides when the sun, moon and earth form a right angle
