But this characterization also fits various kinds of perceptual and linguistic activities that are not usually considered measurements, and is therefore too broad to count as a definition of measurement.
While mechanical waves are caused by wave amplitude and not by frequency, electromagnetic waves are produced by the vibration of the charged particles. When comparing the speed of mechanical and electromagnetic waves, the former travels at low speed.
Mechanical Waves and Longitudinal Waves. There are two types of mechanical waves. The first is longitudinal. The second is transverse. All mechinical wave must go through a medium, such as water, air, and a solid (earth)A longitunal wave is the displacement of the medium is parallel to the propagation of the wave. A good example is a slinky.
