However, the electric wave driving them propagates at he speed of light appropriate for the medium. The electrons move hardly at all at RF/AC frequencies. On the average, they tend to oscillate mostly in place. What travels at the speed of light are the photons emitted by the oscillating electrons. The electrons form the equivalent of a "bucket brigade" for the photonic wave energy. -- 73, Cecil, IEEE, OOTC, *http://www.w5dxp.com Cecil Does that mean that a radiator reduces mass with use because the electrons orbiting around the atom are losing mass? You are basically stating that an electron in orbit is travelling at the speed of light which thus imparts the same velocity to a photon which there fore also has mass since it has the same speed as the electron in orbit! Something wrong there! And for the other gentleman, what exactly is an electric wave? Does it stay in place or does it leave the radiator? Does it have mass such that the radiator gets lighter in use? It is beginning to appear to me that hams are not sure what creats radiation and what constitutes radiation! Art |
