What is the speed of light in a Michelson interferometer?

AI Thread Summary
The discussion centers on the speed of light in a Michelson interferometer, specifically regarding its speed to and from a mirror. It clarifies that the speed of light in a vacuum is always constant at c, regardless of the motion of the source or observer. The original misconception by Michelson and Morley was that light would travel at c+v or c-v depending on its direction relative to the aether. The conversation highlights the importance of understanding that the speed of light remains c, debunking the aether theory. Ultimately, the discussion emphasizes the consistency of light's speed in a vacuum, regardless of external factors.

can someone explain to me the speed of light to the mirror and back from the mirror before reaching the telescope ?? please

I'm sorry, I don't understand what you are asking. Could you elaborate your question a bit more?
 
sorry i shoudl have elaborated more , i mean why the speed of light from the half painted mirror to one of the two mirrors is c-v and c+v from the mirror to the painted mirror??
 
The speed of light in a vacuum is always c. Michelson and Morley erroneously thought that light would travel at c+v if it was moving in the same direction as the aether (which presumably travels at v), and c-v when moving in the opposite direction as the aether.
 
mmm i have read it you are right in everything but in the speed of c and ether c-v when angle between them is zero and c+v when they are opposite but thank you for all your help

Thread 'Question about pressure of a liquid'

I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...

Thread 'Why is the 3 body problem unsolvable? And what will happen if someone solves it?'

I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
