What is damped wave?

A damped wave is a type of wave that decreases in amplitude and energy over time due to the presence of a dissipative force or medium. This means that the oscillations of the wave become weaker as they propagate through the medium or as they are reflected back from boundaries. As the energy of the wave is lost due to damping, the amplitude and frequency of the wave change. Damping can be caused by various factors, such as friction, resistance, viscosity, and absorption. Damped waves have practical applications in various fields, including engineering, physics, and mathematics, and are used to model phenomena such as sound, light, and electrical signals as they travel through materials or mediums with inherent damping properties.
