What is the speed of electricity or lightning compared to the speed of sound and light?
The speed of lightning is somewhere between that of light and sound which is why most scientists would agree that the speed of light and the speed of sound make a good comparison to that of lightning and electricity.
Explain why thunder is heard after the lightning is seen?
Thunder is sound- it travels at the speed of sound- about 1100 feet per second. Lightning is light- it travels at the speed of light- about 186,000 miles a second. The light is faster, gets there first.
Why does lightning first?
The speed of light is faster than the speed of sound, therefore you see lightning first during a thunderstorm, then you hear the thunder. *yikes!* :) ilovecatz1234
How does lightning travel?
Lightning is the exchange of energy and plasma. According to scientist Bruce Steo, lightning moves at variable speeds. Lightning is in fact not light. But as the electronic plasma moves through charged air, it releases light waves. Depending on air conditions, the typical lightning bolt moves at 224,000 mph -- or about 3,700 miles per second.However, the light you see from the lightning obviously travels at the speed of light, which is roughly 670 million mph, or 186,000 miles per second.Lightening travels at 300,000 km per second which is the same speed as light.
Why do you see a flashed of lightning before you hear a clap of thunder?
Because the speed of light travels faster than the speed of sound.

Is lightning or sound faster?
Lightning. Because it is the speed of light.
How fast lightning go?
Approx. 270,000 mph or about 75 miles per second. Lightning creates light but is an exchange of energy and is, therefore subject to friction so it does not travel the speed of light.
Why is it that lightning travels faster than sound?
Light speed is much faster than the speed of sound, ergo the light you see in lightning is visible, before you here the sound.
What is lightings speed?
the speed of light is 300 thousand kilometres a second, or 300 million metres a second. which means it would go around the world 7.5 times in a single second. a light year is the distance that light travels in one year, which is 9.5 trillion kilometres. light is gamma rays, and gamma rays are electromagnetic waves that occur after either alpha or beta decay.
Can you ever stop a train when its going the speed of lightning?
A train couldn't go the speed of lightning. At least not with our technology.
Explain why thunder is heard after the lightning is seen?
Thunder is sound- it travels at the speed of sound- about 1100 feet per second. Lightning is light- it travels at the speed of light- about 186,000 miles a second. The light is faster, gets there first.

Why do you see a lightning flash before you hear it?
Because the speed of light is faster than the speed of sound.
Why is there a delay between the lightning an thunder?
There is a delay between seeing the lightning and hearing the thunder because the speed of light (lightning) is much faster than the speed of sound (thunder). Thus, you SEE lightning first, and then you HEAR thunder later.
How long will it take to cross the universe at the speed of lightning?
I don't know about the speed of lightning, but the fastest you can go is at the speed of light. You can't "cross the Universe" at this speed, because of the accelerate expansion of the Universe. Light that is emitted from any object that is a certain distance away from us - somewhere in the order of 10 billion light-years - will never be able to reach us.
