Homonym: wave (Gesture)
A wave is a disturbance that travels through space and matter, transferring energy from one point to another without permanently displacing the medium. Waves can be found in various forms, including sound waves, light waves, and water waves. They are characterized by properties such as wavelength, frequency, and amplitude.
Waves can be classified into two main types: mechanical waves, which require a medium (like air or water) to travel through, and electromagnetic waves, which can move through a vacuum (like radio waves and visible light). Understanding waves is essential in fields like physics, engineering, and communication.
