Repeating disturbance or movement. Carries energy through matter and space. Vibrations. Anything that moves in a rhythmic patter. Up and down. Back and forth. What is a Wave. All waves are produced when something vibrates. A wave is a disturbance in a medium that carries energy without a net movement of particles.. Ocean . waves are formed as wind blows across the surface of the ocean, creating small ripples, which eventually become waves with increasing time and distance. . 2022-2023 Season.
