It means when you light a match over here, how long it takes before your partner over there
can see it. Just like everything else, it takes time for the light to get from here over to there.
The speed it travels is about 186,000 miles a second, or 300,000 kilometers a second.

Why do people say faster than the speed of light?

Light travels at approximately 186,000 miles per SECOND. That is fast. So the expression "faster than the speed of light" is used to describe someone or something that is really fast (but it's not actually faster than speed of light)

What is the speed of darkness?

Darkness doesn't have a speed. What you are seeing is the light leaving. You could say it's the same as the speed of light but it's really just your perception that darkness is moving but it's really the absence of light.


If I was riding a bike inside a bubble at 4 mph and the bubble was travelling at the speed of light when i turned on the front light on would the light shine in front or behind the bike.?

You cannot go at or faster than the speed of light. Let's say your bubble was going 2 mph less than the speed of light. The way relativity works, you could ride your bike at any speed humanly possible, from your point of view. But your time is slowed down, so from an outside observer, you appear to only move slightly faster (still less than light speed). And if you turn on that flashlight, it will go away from you apparently at light speed, but the outside observer will also see it moving at light speed. It is tricky when you first encounter this.


What is the velocity of violet light?

Have you ever heard of "The Speed of Light" ? Have you ever wondered why it's just a number, and it doesn't say anything about the color of the light ? The speed of all colors of light is the same, as long as they're all moving through the same substance. It's the number called the "Speed of Light", which you should be able to look up quite easily.

When some on say the speed of light what are they referring to?

Light is actually a wave that is emitted from atoms. It radiates outwards, but it must travel to our eyes in order for us to see it. For example, when we look at the sun, the light we see is already eight minutes old since it radiated from the sun. This speed by which it travels has been determined to be 186000 miles per second.

Do you say THE Chinese are ancient people or Chinese are ancient people?

In general, when referring to the entire population as a whole, you would say "the Chinese are an ancient people". To say "Chinese are ancient people" leaves the reference population undefined - are you referring to the entire population of China or are you referring to a select group of Chinese individuals who are older?

Why is the speed of light a fact?

A "fact" is basically anything you can state, especially if such a statement is true. Since you can say "light has a speed", and since that is true, it follows that it's a fact. Light through a "vacuum" is the meaning of "the speed of light." Light through glass is slower.


What travels at approximately 1117 million kilometres an hour?

Speed of light * * * * * Nothing, since the speed of light in vacuum is around 1080 million km/h. In any case, the "speed of light" does not travel!
