Independence of waves

These examples are quite different. Experiments in one cannot be used to make an inference in the other. One is electric flow, the other is photons. The physics are not even close to the same. Which one do you want to talk about? Current flow in lumped circuits is assumed to take place instantaneously, i.e. faster than light speed. In a DC steady-state, there is no acceleration of carriers and therefore, no photonic particle flow so the above shortcut works in that case. It doesn't work in RF distributed networks where photon generation and absorption never ceases. One of the boundary conditions for EM wave flow is that is can never exceed the speed of light c(VF). One needs to know when one's model has become invalid for the task at hand. -- 73, Cecil http://www.w5dxp.com |
