B Does this experiment prove that light speed is actually faster?

AI Thread Summary
The discussion centers on the misconception that light speed is instantaneous, illustrated by an experiment using a taut clothesline and clothespins. Participants clarify that the movement observed is not instantaneous but rather occurs at the speed of sound in the clothesline, which is significantly slower than the speed of light. The experiment does not involve light, making it irrelevant to discussions about light speed. Critics emphasize that the scenario does not qualify as a proper experiment without rigorous testing. Overall, the thread concludes that the initial claim lacks scientific validity and understanding.

Some people thought light speed is actually instantaneous which can be demonstrated by doing an experiment involving a taut clothesline and two clothespins. On each ends of the taut clothesline, put one of the clothespins on both ends and touch one of the clothespin will make the other one at the other end moves instantly. Does this experiment demonstrated that light speed is instantaneous?

What would make you believe that this is true?

It is far from instant. It would move at the speed of sound in the close line which is far far far smaller than c, and not even remotely instantaneously.

Not instantly, but is delayed by the speed of sound in the clothesline, which depends on the tension.
 
A. This is not an experiment. It's not an experiment unless you do it.
B. Light is not involved. How can it tell you anything about light?
C. You have a history of low quality thread starts. You also have a history of wandering off when asked clarifying questions. Neither will help you understand.

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
