Question

What are some examples of mechanical waves?

Answer 1

Hint: A mechanical wave is a type of wave which has an oscillation of matter, and hence, it needs a medium to transfer energy. While waves can yield long distances, the movement of the medium of transmission the material is limited. Therefore, the oscillating material doesn't move far away from its initial equilibrium position. A mechanical wave requires an initial energy input. Once this initial energy is given to the wave, the wave travels through the medium until all of its energy is transferred or exhausted. In contrast, electromagnetic waves require no medium, but can still travel through one.

Complete answer:
Mechanical waves are basically divided into several types but we can basically define three types of mechanical waves which are: transverse waves, longitudinal waves, and surface waves. Some of the most basic and useful examples of mechanical waves are water waves, sound waves, & seismic waves.
Mechanical waves do not exist without medium as they need any medium to transfer energy and propagate through it. When the energy of mechanical waves gets exhausted, they disappear. We all have seen that water ripples disappear after some time in ponds or in lakes. Energy of mechanical wave gets decreased when they propagate through the medium

Note:
Mechanical waves transport energy. This energy propagates within the same direction as the wave. Any kind of wave (mechanical or electromagnetic) includes a certain energy. Mechanical waves are often produced only in media which possess elasticity and inertia. One most important property of mechanical waves is that their amplitudes are measured in an uncommon way, displacement divided by wavelength.
