In physics, the word wave is used to conceptualize a traveling disturbance that transports energy from one location to another. This transport of energy without matter is a common physical phenomenon.
The material the energy travels through is the medium. The movement of the energy is called propagation. We can find some examples of waves inside a microwave or radio waves.
Example of wave
Imagine a pool of water in which the surface is perfectly smooth. Now imagine that you throw a stone:
Right at the point of impact, you will immediately see ripples appear that move from the point of impact and move away in concentric circles. That’s waves
