A wave is a disturbance that travels through a medium, often water, transporting energy without the medium itself moving significantly. Waves can be caused by various factors such as wind, gravitational forces, and seismic activities. They are characterized by their wavelength, frequency, amplitude, and speed. Common examples include ocean waves, sound waves, and light waves.
