text: Some of the earliest experimental clues that c must be constant for all observers were derived from Maxwell's equations.
text: Albert Einstein went through several versions of light speed theory between 1905 and 1915, eventually concluding that light speed is constant when gravity does not have to be considered but that the speed of light cannot be constant in a gravitational field with variable strength.
text: In this expression, c is a constant equal to the speed of light in a vacuum.
text: I would to conclude be happy to have in your reply some links and references to actual experiments being carried out and their results that prove that light speed is a constant (not using units of measurements linked to the speed of light of course).
text: If the mass weren't zero, the speed of light would not be constant; but from a theoretical point of view we would then take c to be the upper limit of the speed of light in vacuum so that we can continue to ask whether c is constant.
text: This provides a very short answer to the question "Is c constant": Yes, c is constant by definition!
text: This provides a very short answer to the question "Is c constant": Yes, c is constant by definition!
text: If it wasn't zero, the speed of light would not be constant; but from a theoretical point of view we would then take c to be the upper limit of the speed of light in vacuum so that we can continue to ask whether c is constant.
text: Your other question is whether there's a way to derive that c is constant in all inertial frames.
text: I think the discussion earlier in the thread was more about whether c is constant as viewed in different frames, not as viewed over time.
text: Now that you know that, you can relate wavelength to frequency since c is constant.
text: Follow-Up #5: Why assume light speed is constant?
text: Im going back a few steps, but i was not satisfied with your answer of how it has been proven that lights speed is constant.
