In one chapter light (and radio waves) is like photons, in the next chapter like EM waves and in next like acoustics. EM is the only example of transversal waves. So it must be in teaching program. But we try to help Peter. He wrote: "I begin to appreciate a comment made by a fellow radio amateur and technician that antenna theory was 15% science and 85% black magic! " It seems that you are sure that radio waves are transversal. It is impossible to help you (Maxwell was full of doubts). May be that somebody consider the Acoustic analogy and the black magic disappear for him. S* maxwell may have been full of doubts, and Einstein wasn't able to see the experiments that have proven his theories, Maxwell did EM, Einstein did the photons and somebody else the acoustic analogy. but we have seen them well tested and accepted over the years. All of that three ( all three are in textbooks) are well tested and accepted but only in some extend. May be that after some time only one will be fully accepted. Which one do you designate? if you think that 85% is black magic then you have lots of learning to do to fill in that 85% gap in your knowledge. I designate the acoustic analogy and do not see any gaps. They who designate EM or the photons are in constant trouble for more than 100 years. S* you may designate away, that doesn't make it any more correct. *the only things that the acoustic, water, and em radiation has in common is the sinusoidal characteristics and that superposition works. because of those two you can get similar interference patterns from all 3 types of waves. *that doesn't mean the underlying physics are the same. Oscillating compressible gas create .the standing waves in the tube with the closed *end. The oscillating compressible electron gas create the standing waves in open circuit (antenna). Is not the same physics? S* no |
