How fast does light travel through a fibre optic cable? But the higher core index, also means a slower light speed in the fiber You can actually determine much of this without knowing the fiber index, if the manufacturer specifies the "numerical aperture" of the fiber, which is a measure of the maximum acceptance angle of the cone of light which can propagate along the cable
Can quantum entanglement travel faster than the speed of light? Recently I was watching a video on quantum computing where the narrators describe that quantum entanglement information travels faster than light! Is it really possible for anything to move faster
Would time freeze if you could travel at the speed of light? 68 I read with interest about Einstein's Theory of Relativity and his proposition about the speed of light being the universal speed limit So, if I were to travel in a spacecraft at (practically) the speed of light, would I freeze and stop moving? Would the universe around me freeze and stop moving? Who would the time stop for?
special relativity - Why does speed of light have to be constant . . . In order for Alice to see the speed of light as a constant value, time slows down and length expands (in forward direction) thus keeping the speed constant In the course I'm doing, the Professor tells that this constancy of speed of light could be more generally referred to as, "Principle of wave constancy"
Why does red light travel faster than blue light? One simple answer (and there are actual, deeper physics answers) is that the light interacts with the material, and those interactions are wavelength dependent And, red light doesn't always travel faster than blue light - that is material dependent through those interactions mentioned above
How did Einstein know the speed of light was constant? Maxwell's theory of electromagnetism - speed of light is constant Galilean invariance - the laws of motion have the same form in all inertial frames Galilean transformation It turned out that the last one (Galilean transformation) was wrong Einstein considered the first two correct and built the special theory of relativity
special relativity - How is the speed of light constant in all . . . Analysis: Assuming the speed of light is constant for BoxGuy relative to himself, the time between Pulse and Reflect is equal to the time between Reflect and Return This is because the distance the light travels relative to him is d in both cases
Why is the speed-of-light the upper limit rather than the speed of . . . The reason is partly historical accident, and partly experimental support, but in the end a certain salient property of light itself James Clerk Maxwell inferred, from his laws of electromagnetism, that there exist electromagnetic waves Computing the speed at which they travel, he found that this speed was in close agreement with the observed speed of light And so he conjectured that light
speed of light - The famous drop of $c$ - Physics Stack Exchange However, the value of the speed of light (in vacuum) itself is of course unaffected by any particular definition of units He [the speed of light (in vacuum)] might still change, That appears doubtful
