"Well in scientific terms, a wave is a disturbance that transfers energy from one way or another. Like transverse waves are where particles move perpendicularity to the direction the wave travels."
"Uhh, okay then. I guess tell me more? You're such a nerd Alona."
"Well thank you very much. I was going to continue you dork. Anyways, you see the buoys over there? You can calculate the timing of them moving by measuring the wave length and the wave period. Dang I really am a nerd."
