I have skimmed relevant links in wikipedia, and some external links regarding electromagnetic fields, but would like a simple (I'm no physicist) answer to the following question that I have.
When one, for example, takes two strong permanent magnets and aligns so that there is repulsive/or...
101 question, probably could find out by doing research but had luck on this forum on another topic, so ...
If electrons have 'negative' charge and nucleus is 'positive' what force keeps them apart ? Is it just a matter of them sort of 'orbiting' like the moon around the Earth where 'falling'...
Thanks for the offer, but it is not the math (i am capable of the simple math involved) but the notion that light maintains the momentum of the emitter. I am willing to admit I was wrong all these years, but just one last confirmation. I made a pic called trainc.jpg which is plan view of a...
Ok thanks, all this time I did not know that a moving emitter transfers it's momentum to the light being emitted. I thought for instance if an emitter was moving v in x-axis direction, and fired a photon perpendicular say exactly in direction of y when it was at say x coordinate 10, that the...
Thanks again for the links, it seems there is consensus on this that T1a is what happens.
So part 2 of the questions becomes the following. In the trainb.jpg picture I have depicted a scenario where the train car is traveling right past a light pole with the exact same type light source. Both...
Sorry, I should have been more explicit please look at picture. I realize that someone on the ground would not actually even see the light pulse or photons hitting sensor, so I think aberration is not involved here. What I meant is from the observer's perspective if he was informed that the...
I guess my title was wrong for part 1 of my question, but not part 2 which is dependant on the answer to part 1. But the question is still the question. Thankyou for your reply.
I would like confirmation of this though, is this correct that the light travels in a 'angled' path if viewed from...
This is a two part question. Part 1: I am embarrassed to ask but if someone could please help me. I was thinking about a train car moving at a constant speed which had a simple apparatus onboard. A light source on a pole which emits light straight down only (say a laser of some kind). Below the...
