Hey Harry, glad you were able to make the coffee clutch. I wonder if you could help me out with something. Well I don't climb towers! Harry quickly stated. No, I need help in understanding radiation. I haven't studied electronics, I am a lawyer! Well it should be easy for you Art It is just a question of learning new words, definitions, then putting them together in such a way that every body just nods their head understandingly. Harry I never said I was a good lawyer. Stop laughing! I just want to find a way to understand it with out having a Doctorate using every day words that even I can understand. I don't understand cars and they are difficult things to piddle with but I still enjoy driving it and enjoying the ride.
OK Art I am not sure that I put all of this on one serviette or napkin as we call it over here but since you started off on cars lets continue with that line of thought. That car race that was over at Indy the other day had a turn at each end of the track. Yes, but I thought we were talking about radiation!
Will you shut up Art and just enjoy the ride for once? When we started to turn at the corner you slid all over the place in your seat as we went around. Well I was resisting! Resisting what? Flying out of the car you dummy! Didn't you hear the tires screaming? Well they always do that at turns, otherwise they would fly off the track. But they don't do it on the straight part only on the turns don't they?
Exactly Art, that piece of rubber left on the road is called radiation Oh come on Harry! I am not totally stupid. You're a layer! Quit it Harry. OK Art. But think about it. The car leaves rubber on the road for the same reason you slipped around on the seat and was resisting falling out of your seat You were one big resister.
What has this all got to do with radiation, I know you used the electrical term 'resister' but you're playing with words. No I am not Art, settle down. Let us think of the car as an electron, a big one but any way it fits what we are talking about. Not really Harry, isn't it all supposed to be about frequency and you haven't even mentioned that. You're right Art, I have been using the term lap and lap times, if you wont to use the term frequency of arrival at the starting line be my guest!
No, I don't intend to be rude but I was talking about that mathematical thing that they talk about at the club! Art, for crying out loud it is the same thing! All they are talking about is the time it takes for a car to get round the track, think car and track times but don,t say it out loud say 'electrons' and 'frequency'. And they will nod their head. I bet they don't!
Well you cant expect to be a scientist over one cup of coffee, are you going to pay for a fill up since the other guys haven't got here yet? OK, but something is not quite right here. When I have looked at books on dipoles they show a curve of current going along it, so even if we have a straight track it is radiating on the straight part just like that dipole, thats why they put the current curve on the drawing! Well I suppose we can talk about something else or you can read your book ART. Have a fill up of coffee Harry. Do you take sugar? Yes I do, Thanks Any way I Know What you are talking about, it is just the way they play the game so the current is always nothing at the end of the antenna and it is easier to draw. they match the speed of the car with the size of the race track so that the frequency of the laps are the same.
Just remember, radiation is the rubber you left on the road when you accelerate hard, just stick with that and accept it Well what about the rubber you leave when you brake hard? you are not accelerating the car, sorry, electron? Art, will you stop resisting and go with the flow? You raise an interesting point though. There are two types of radiation, electric for accelerating and the magnetic wave type for de-accelerating.
When you come to think about it, you can't have one without the other. Fortunately they are created at different times and don't interfere with each other. Your right of course but radio ignores anything that is not connected to a accelerating electron, it's still there, you just ignore it.
Well that's all very interesting Harry but I use a loop antenna so the electrons don't have two turns per lap and yet that radiates. So you are all screwed up because you are saying radio waves are just a bunch of pulses, and that has to be wrong! Just listen to the WJBC
Well Art let us talk that one out. When the car races around a circular track it still wears the tires out, it just spreads it all around the track so, I suppose the car is actually accelerating all the way around the track, Hard to understand but I can accept it. If the car, oops electron deviates from a straight line then it radiates. Thats right! Your loop radiates doesn't it? Yes it does, Harry......... But not in pulses.
Art, they don't just run one car at Indy, there's a whole bunch of them going around, bumper to bumper, every one of them looses a bit of rubber at the turn, its like a continual shower so to speak. Any way, I see that the others guys have arrived. Well just one more quick question Harry, What happens when the electron, oops, car, races on a track of a different size?
All hell breaks loose Art. That car is so used to turning at a certain time that it is going to turn at the same time regardless and, of course, all hell breaks loose when it turns when there isn't a turn. Collisions, cars going each and every way and a bunch of magnetic waves (burnt rubber) generated so that the electrons get all jammed up. Sometimes so bad that the race comes to a halt... and thats your transmitter that went up in smoke. Always, make sure that the track is the same size to match the speed of the car if you want to go around at the same frequency. Just like antennas.
Thanks for the help Harry. Could you come early next week again Harry? I want to know how the cars become airborne!!
