Waves are vibrations or oscillations that travel through a medium, such as air or water. Waves can have different shapes, sizes, and speeds. Waves can be seen in ocean waves, sound waves, and light waves.
What are Waves?

A wave is a disturbance that propagates through space and time, transferring energy from one point to another. Waves can travel through any material, but they need a medium, such as air, water or some other substance, to do so. There are two main types of waves: transverse waves, which move the medium perpendicular to the wave’s direction of travel, and longitudinal waves, which move the medium parallel to the wave’s direction of travel.

When a wave reaches shore, the water particles in the wave actually move in a circular motion. Waves can travel up to 800 miles per day. Surfers can ride a wave for up to 30 seconds.

Question: Why do waves form in the ocean? Clues: • Waves are caused by the wind pushing on the surface of the water. • The surface of the water is pushed in the direction that the wind is blowing. • The energy of the wind is transferred to the water and causes the surface to rise and fall in waves. In pairs: Select and solve one of the tasks: A. Draw what happens when the wind pushes on the surface of the water. B. Explain why the wind causes the surface of the water to rise and fall in waves.
