The two waves emitted from the dipole (ACOUSTIC OR ELECTRIC) are "polarized". You can experimentally determine the plane in which the dipole is. The same is with more sources. S* they may have the same patterns for some cases, that is why they are used in lower grades, to keep the explanations of waves simple for those who don't have the mathematical background to understand the full detail of it. *but pattern does not show polarization. *by matching an interference pattern you are not showing how a wave is polarized, You assume that radio wave is transversal. Such are polarised. But such are only in Maxwell's Hypothesis. Radio waves from the ends of the *dipole are coupled. The both are in one plane. Radio wave from one end is spherical. only that superposition principles work for both types of waves. *show me an experiment where a sound wave is polarized, Sound wave is not polarised. Sound waves from "dipole" is. that one i would like to see. you might want to start with a couple of these:http://en.wikipedia.org/wiki/Wavehtt...rial_files/Web... In above no directional pattern for sound dipoles. "Polarized" means directional. Are all radio waves directional? S* this discussion is worthless until you go back to school and learn the basics. |
