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.
Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges. Explain the self-perpetuating behavior of an electromagnetic wave. Electromagnetic waves consist of both electric and magnetic field waves. These waves oscillate in perpendicular planes with respect to each other, and are in phase.
