all waves work similarly, so although we are talking about ocean waves here, the same information would apply to any other waves you might discuss in science classes. live background ocean. ocean waves transport energy over vast distances, although the water itself does not move, except up and down. this may surprise you, but if you think about it, once you are past the breakers on your raft, you pretty much just bob up and down. (you might drift up the beach….we’ll get to that.) this orbital motion is explained in the figure below: there are waves of all sizes and shapes rolling into the beach at any given time. if they’re not stopped by anything, waves can travel across entire ocean basins and so the waves at your beach might be from a storm half a world away. the most familiar ocean waves are caused by the wind. live background ocean.
these are wind-driven waves. this sort of motion is set up anytime two fluids rub together, and remember that the atmosphere is essentially fluid. waves caused by underwater disturbances such as earthquakes, landslides, or volcanic eruptions are called tsunamis. these waves are typically tens to hundreds of kilometers long. the gravitational pull of the sun and moon on the earth causes the tides which are actually tidal waves. we’ll get back to that. one waves motion is completely independent of any other wave motion. when two groups of waves meet, they pass right through each other. this is obvious if you consider light and sound waves. when two people talk or your child has both the tv and the stereo on, you can hear both. one set of sound waves doesn’t garble the other. likewise you can see two objects at the same time. live background ocean. what does happen, though is that waves can either add up or cancel each other out as they pass through one another. this property is called superposition. if a crest from one wave happens to line up with the trough of another, they cancel each other out. this is called destructive interference. live background ocean. if two waves line up crest to crest or trough to trough, they add up. this is called constructive interference. this is why waves at the beach are all different sizes. there are lots of different wave groups coming in, and they’re interfering with each other in different ways.
