How could one distinguish longitudinal waves from transverse waves, that is to say, how could one distinguish the Tesla wave from the Hertz wave?
For all kinds of waves there exist at least one vortex variant. The variant for radio waves, for instance, is thermal RF noise, which, according to longitudinal electromagnetic wave theory, propagates with the velocity that is greater or less than C. The velocity is the product of frequency and wavelength: v = f λ If one wishes to determine whether a wave is transverse or longitudinal then of the three variables v, f, and λ (lambda) at least two of them have to be measured. For any specific wavelength the frequency is proportional to the velocity of propagation. [Konstantin Meyl] There are three systems to be brought under consideration here, each one being set distinctly apart from the others by the design of its launching structure. For the purposes of this discussion the three types of wireless transmitter are defined as, 1) The radio wave or Hertz wave transmitter that uses a dipole antenna radiator in free space to launch radio space waves; the dipole radiator is vertically polari
