Wave Lengths!! (:

In class, we have recently been studying waves. A wave transfers energy from place to place from a disturbance in something. For example, if a human jumps into a pool, their body (being the disturbance) makes the water move in up and down motions. Those up and down motions are the waves. Each wave has a crest (the highest point of the wave) and a trough (the lowest point of the wave. Each wave has a wave length, a frequency, and a speed. The wave length is how far the wave can go before it reaches its end. Its frequency is how many waves pass a point in a certain amount of time, and the speed is how fast it goes. In society, waves are important because although you cannot see them, they are everywhere. Sound waves, waves in the ocean, etc. etc. Even if you cannot see them, they are always there.
