If light is the quickest thing known to man how fast is dark ??

Answer 1

Dark isn't very fast at all, in summer i can turn the light switch off & be in bed before it gets dark.

Answer 2

Hmm, a few wikipedia swallowers on here again. Depends what you mean by dark. Which bit of the EM spectrum? Yes absence of EM radiation at 2 and a bit times 10^8 m/s is right for lack of light but it's almost impossible to find true darkness anywhere in the Universe as there is always hydrogen radiation at just over 1GHz.

Answer 3

by the way time is the quickest thing known to man.
2ndly dark is when there is no light. so the speed of dark is equal to light meaning that as soon as the light is turned off, dark is there

Answer 4

This question gets asked about once a week, as an aside.

Anyway, dark isn't a substance or form of energy - it's just the absence of light.

Since light travels at 2.9979 x10^8 m/s, and dark is the absence of light, and since an area becomes dark as soon as light moves off of it, you can reasonably say that the speed of dark is equal to and opposite in sign from the speed of light.

Therefore, the speed of dark is -2.9979x10^8 m/s.

Answer 5

Probably just as quick as the light. As fast as the light can leave, the dark can arrive.

Answer 6

Depends what you class as dark!!!-Light travels at 186,000 miles per second-ish,and we can see it because our eyes can pick up light in that range-or frequency of the visible spectrum.
Dark is just a lower light threshhold of light as far as our eyes are concerned-therefore we can't see it, but it travels at exactly the same speed-which is why our armed forces use night vision goggles-they just intensify the available light-which our eyes cannot pick up-and multiply it to give us some sort of vision,albeit not very good!.

Who makes a decision what's blasphemy? The song makes use of Christian references very almost casually, and that constitutes blasphemy for many. The lyrics are so densely packed with references that have different meanings that McLean could not have been doing something informal in it. The 'Father, Son and Holy Ghost' are the '3 adult men i comprehend maximum', which argues against a private (to McLean) counter-Christian examining yet does *enable* for the translation that it references society's circulation removed from favourite faith. a query right here is how plenty the song is particularly appropriate to the 60s counter-custom and how an excellent number of it fairly is approximately alterations in society specifically. yet i think of this is extra of a passing remark interior the song. My impact is that if McLean would desire to in all probability imbed extra beneficial than one meaning/reference in a observe or line, he did. i think of the *time-honored* use of religious imagery is the passing of the sense of fact and ease (the united states of america of america of apple pies) via fact the counter-custom technology lost the desire that they might have the skill to hold forth significant and significant exchange. for many little ones, song had replaced faith via fact the ability during which social values have been suggested and transmitted, in spite of the undeniable fact that it hadn't succeeded in bringing appropriate to the was hoping for utopia. The musicians (and perchance political figures (Kennedy, King and Kennedy) who have been exhibiting the beneficial way forward had died, bought out or broken up - Dylan went electric powered, then stopped traveling after an twist of destiny, then refused to place in writing protest songs; the Beatles ("All you elect is Love") disbanded and the Stones ("Sympathy for the devil") became the main influential working band, the beneficial properties of the Civil Rights circulation have been overshadowed through race riots in different cities in the process the summer season of 'sixty seven, whilst Haight-Asbury replaced into heaving with the "summer season of love". examine verse 6 with that final in suggestions. Neither song nor faith had a answer for the continued social problems.

Answer 8

The speed of dark is 0 meters/second.

Answer 9

Dark is at least as fast as light. It has to be or it would be caught. Since dark always runs away from light and is never caught, then it must be at least that fast.

Answer 10

the same speed .lol
turn out the light it`s dark.
