The process of transferring energy through a medium via vibrations is called wave propagation. This phenomenon occurs when sound, light, or seismic waves carry energy from one location to another, causing oscillations in the medium (such as air, water, or solid materials). In sound waves, for example, the vibration of air particles transmits energy that can be perceived as sound by the human ear. This process is fundamental in various fields such as acoustics, telecommunications, and geophysics, and helps explain how different forms of energy travel through different environments.
