Answer:-
Mechanical waves are waves that require a medium to travel through. Common examples include sound waves, which move through air or water to let us hear; water waves, like those seen in oceans or lakes; and seismic waves, which travel through the Earth during earthquakes. Slinky waves in physics experiments also show how energy moves through a spring. Another example is vibrations in a guitar string, where the energy travels through the string and produces sound. All these waves transfer energy by making the particles of the medium vibrate—without a medium, mechanical waves can’t move at all.
