sorry I was thinking of the train as a rigid body. i see what you are talking about now.

if there is no friction then those are the only 2 equations that you need, because the length of l does not matter.

Ok, i knew i was missing something i was reading ##c## as ##c_s## Thanks

As intuitive and trivial as it may be i would feel much more comfortable about educating people that the transverse doppler effect does not exist for sound if there were experimental proof, rather than relying on intuition. I do not know. I probably wouldn't of ask the question if i did. I...

I have been trying to find an per reviewed article where it is actually tested that sound does not have a transverse Doppler effect. I figure that its probably do to my lack of resources. if it is could somebody give me a link to the article i would appreciate it. If not, i must ask why has it...

Agreed, I think the wording in my last statement was bad. I will try and think of a better way to word it. But the principle is I want to know if both observers agree on the position X1 (in the stationary observer's frame) of the front of the train when it's struck, and the position of the...

Nope (In the simplest form of the experiment) I think both observers would agree that one lightning strike hit the front of the train and the other hit the back. let's say that "event A" is the moment that the moving observer sees the lightning strike the front of the train and "event B" is...

I was reading about (The train-and-platform thought experiment) from https://en.wikipedia.org/wiki/Relativity_of_simultaneity and was wondering a couple of things. 1.) Would the observer on the train agree with the stationary observer that event A and B happen at the same place in the stationary...

I am by no means suggesting a single magical "medium". But does by assigning a charge density and current density to a medium suggest that light is using a medium? kind of like how for sound we assign a coefficient of stiffness and density. To calculate how fast it should move through a material.

I do understand that they were trying to detect the medium as to how they understood it and there experiment failed. Which means that there understanding of the medium was wrong. Instead of abandoning the aether model they tried to tweak it a little to work with their understanding. I figured...

Does that mean that a vessel that has a vacuum inside of it does not move? Since the vacuum inside the vessel can't have a velocity or motion the vessel that contains it cannot have velocity or motion or it will brake. I get what the statement is trying to say. You can't move nothing. Since a...

I have not seen any MMX have been done in open space, where the medium around the interferometer is moving. I tried to find MMX done under a vacuum but i could not. I would assume that the experiment was done here on earth. So it would be in a pocket of vacuum where there would be no relative...

Not really, from what i read about complete aether dragging hypothesis is " aether is completely dragged within and in the vicinity of matter". In that model, Aether is the only substance that light can use to travel. I am consider that light is using air as a medium. So experiments like oliver...

Normally in explaining the aether model of light it is said that all waves need a medium, so just like sound uses air, light uses the aether. To my understanding sound can travel through gas, liquid and solids just fine without air being partially entrained in the materials. Sound does not use...

Exactly there is no difference between a 440Hz sound with both observer and source stationary and a 440Hz sound that is produced by relative motion. According to what I have read hear you would not need any extra information because just from the sound you can measure the frequency and...
