Waves are an energy transfer that moves through a medium such as air, water, or sound. Different types of waves exist, such as mechanical, sound, electromagnetic, and seismic. The study of waves is important for understanding how sound moves and how electricity and light travel.
The Science of Waves

Wave: A wave is a disturbance that travels through space and time, transferring energy from one place to another. Wave Frequency: Wave frequency is the number of complete waves that pass a certain point in a certain period of time. Wave Amplitude: Wave amplitude is the maximum displacement from the equilibrium or rest position of a particle or medium that is caused by a wave.

Waves are energy that travels through a medium, such as water or air. Waves transfer energy from one place to another. Waves can travel through solids, liquids, and gases. There are many different types of waves, but they all share many of the same properties.

Waves are caused by the transfer of energy, not by the actual movement of water. The wavelength of a typical wave can be as small as a few millimetres or as large as hundreds of kilometres. The speed of ocean waves can range from 0.2 metres per second to over 800 metres per second depending on the type of wave.
