The medium is the substance through which sound waves travel, such as air, water, or solids.

Kinetic energy is the energy possessed by an object due to its motion, which can be harnessed to generate electricity in power plants.

Absorption is the process by which a wave is taken in by an object, resulting in a decrease in the wave's energy.

Destructive interference occurs when two waves meet and cancel each other out, resulting in a reduced amplitude.

Frequency refers to the number of wavelengths that pass a fixed point in one second, measured in Hertz (Hz).

Wavelength is the distance between successive crests or troughs of a wave, typically measured in meters.

Reflection is the bouncing back of a wave when it hits a barrier, while refraction is the bending of a wave as it passes from one medium to another.

Constructive interference occurs when two waves meet and combine to produce a wave with a larger amplitude.

Amplitude is the maximum extent of a wave's displacement from its rest position, indicating the wave's energy.

A power plant converts various forms of energy into electrical energy for distribution and use.
