SUMMARY

A mechanical wave is not merely a sinusoidal graph of a single particle's motion; rather, it represents the collective displacement of multiple particles, resulting in a wave-like pattern. This phenomenon is described by the wave equation, which models how a function varies with position and time, exemplified by the equation y(kx-vt). While physics provides a framework for understanding waves, the philosophical implications of what a wave "is" extend beyond scientific explanation. For further reading, refer to the linked Wikipedia article on waves.

PREREQUISITES
  • Understanding of Simple Harmonic Motion (SHM)

What is a Wave?

Like,if i think of a particle doing a SHM, then i imagine a Particle going up and down continuously and its graph is a sinusoidal wave. But in case of Mechanical Waves, i am not really able to get the picture. Hence my question,

Is the Wave just a Sin Graph of a single particle or is it the way the particles displace themselves which in turn gives a wave like pattern?

It's a solution to the wave equation. As for what it "is", physics can't answer that. It's a model, sure, but it happens to describe the very real phenomenon of anything which is a function of position and time like y(kx-vt). Philosophy must answer the rest, not physics.
