I was reading about the equivalence principal and was curious how it handles a electron in the accelerating rocket vs one on the earth...seems the one in the rocket should radiate a frequency, just wondering what frequency the Earth one would give off. I THOUGHT it would be some kind of simple...

Really? Can't they measure this? Say take a vacuum tube and shoot electrons one at a time down it and measure the waves given off? A old tv with an electron gun has accelerating electrons, does it emit waves?

Say I have a electron in space, its accelerating along say the x-axis at 10 meters per sec^2, what frequency of light does it emit? Thanks!

Ummm...If time dilation and length contraction due to velocity are not expressed as a curvature of spacetime...I mean then how d you express them? What are they? Come on its a 4d coordinate system, you can exchange the time dimension for any of the others x1,x2 or x3

Remember that when Maxwell/Gauss created the laws, the concept of relative frame of reference was not understood like it Actually you'd be surprised how much length contraction is the cause of a magnetic field when you are considering a moving charge. There is a good youtube video showing the...

Any time there are two objects which are moving relative to each other, there is a space time curvature stress between them, created when one or both of them was accelerated to created the delta V between them. This curvature manifests itself from various perspectives as either a magnetic field...

Is that the same for the proton? Does its field also transform to cancel a identical magnet next to it from the same motion? Say both particles are in the S end of their respective bar magnets fields... Now the electron gets a magnetic field and the proton also gets a magnetic field around it...

Just trying to understand how a stationary electron next to a bar magnet will stay stationary if I start moving towards both of them...a magnetic field appears around the electron from my relative motion, a charge must appear to cancel out the magnetic field?? Or picture 2 identical bar magnets...

So I understand that a charged particle moving relative to me has a magnetic field, and does not have one if its stationary relative to me... So is it true that a magnet moving relative to me has a charge? Say I took a bar magnet and threw it away from me way out in space, would it acquire a...

I'm still a little confused (not being a physicist I assume this is normal :-), that my accelerometer shows a steady 9.8m/s downward, yet a electron at 'rest' with me does not seem to radiate anything, So I guess if I was in space accelerating at 1G in +X direction and a electron is also...

Is being in a gravitational field the same as accelerating? Perhaps that's another question. Though I wonder are two frames of reference the same if both are accelerating at the same rate?

AHHH I get it, so my frame of reference is invalid because I'm accelerating

I know its frustrating to have someone who's not up on maxwell's equations etc, but either 1 of three things must be true... 1. I hop up and down and see a wave get emitted, and the stationary observer does too 2. I hop up and down and nothing gets emitted at all (this is my guess), even though...

ok, I'm not sure about that, just curious if a em wave gets generated by the moving electron (my frame of changing reference) and if it does, does it still exist when I stop hopping?

Nope...but the question is, is a EM wave emitted? When I stop hopping, does a EM wave exist? Say I hopped for 4 seconds, a emwave has traveled quite far in that time, does it cease to exist when I stop hopping?
