-- transport of energy
-- wavelengths equal to their speed divided by their frequency
-- frequencies equal to their speed divided by their wavelength
-- periods equal to the reciprocal of their frequency
-- speeds that are determined by the characteristics of the medium
<span>Extremely powerful single waves have no effect on ships at sea since the depth of water allows the energy to be distributed over hundreds and thousands of feet. In deep water, the bigger the wave, the faster it moves and the slower the surface changes height. As the wave gets into shallow waters, it slows down and can start to pile up to large heights.</span>
One thing I think we must put in the capsule is our pictures. Very necessary, so that other inhabitants would see how we look like.
