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.
