Waves are a fundamental concept in physics that involve the transfer of energy through a medium or through space. There are several types of waves, including mechanical waves (such as sound waves and seismic waves) and electromagnetic waves (such as light waves and radio waves). Waves are characterized by their wavelength, frequency, amplitude, and speed. The study of waves encompasses various branches of physics, including wave mechanics, wave optics, and wave propagation. Waves play a crucial role in a wide range of phenomena, from the behavior of ocean waves to the transmission of information through wireless communication.
