Although oceans cover over 70% of the earth’s surface, only in recent years has oceanography become a major science. Sound waves are widely used to explore the oceans, because they travel much better in sea water than do light waves. Likewise, sound waves are used, by humans and dolphins alike, to communicate under water, because they travel much better than do radio waves.
