Question
What is a mechanical wave? Explain.
✓

Answer


A mechanical wave is a wave motion in a material medium.
Such a wave originates in the displacement of some portion of an elastic medium from its normal position. This causes the layers of matter to oscillate about their equilibrium positions. Because of the elastic properties of the material, the disturbance is transmitted from one layer to the next and so the waveform progresses through the medium.
