I have an idea that I've tried to express on this forum before but without success. There's a lot of reasoning behind the idea so it won't do no good just blurting it out. I want to lead you and see if you reach the same conclusion... So here goes... First question... In classical physics, how would the behaviour of the electromagnetic wave emitted by a charge differ depending on these three types of oscillation patterns ? As you can see, all oscillation patterns have the same frequency, which would give all three emitted EM waves the same wavelength, correct ? Now, if all waves would have the same wavelength, would they differ in some other way perhaps ? Because they're emitted by charges oscillating in different ways, one (I) would expect them to.
