Wave Propagation
Wave propagation refers to the movement of energy through different media—such as air, water, or solid materials—via waves. In acoustics, sound travels as pressure waves through air; in electrodynamics, electrical energy moves as electromagnetic waves, even in a vacuum. Physical acoustics studies how sound interacts with materials, while seismology focuses on seismic waves generated by earthquakes, helping us understand Earth's internal structure. Essentially, wave propagation involves the transfer of energy and information across distances, influencing many natural phenomena and technologies, from music to telecommunications and geological studies.

Wave propagation refers to how waves travel through different mediums, such as air, water, or solids. When energy, like sound or light, is generated, it creates vibrations that move outward from the source. These waves can be mechanical, like sound waves that require air to travel, or electromagnetic, like light waves that can move through a vacuum. The speed and behavior of a wave depend on the medium it travels through, as well as factors like frequency and wavelength. Understanding wave propagation helps explain various phenomena, from music and radio signals to ocean waves and light.
