Best Answer

Light travels at 186,000 miles per second in a vacuum. So the light from a flash of lightning travels at the speed of light in air, which is slightly less than the speed of light in a vacuum (e.g. space)

But lightning itself travels nowhere near as fast as the speed of light. Lightning is an electrical discharge and is bound by the laws of physics. Its speed depends on many factors, including the conductivity of the medium it is travelling through. Careful scientific measurements of many lightning flashes have revealed that the electricity moves at different speeds at different stages of its journey in the lightning flash. Also, its returning upstroke is much faster than its downstroke.

Speed of Propagation

The Guinness Book of Answers indicates maximum speeds around 87,000 miles per second. Also, the US Department of Energy gives the speed of lightning as 93,000 miles per second, which may be based on the 'half the speed of light' principle. Neither is considered accurate for atmospheric discharges.

Observed Velocity

Propagation of high-altitude lightning observed from space was measured at a speed of 50 kilometers per second (112,000 mph). This is considerably slower than the 670 kilometers per second (1,500,000 mph) maximum return stroke velocity reported in an IEEE report in 2006. In a paper published in 2007, wide variations in stroke speeds were reported, up to 4000 kilometers per second (9,000,000 mph). While incredibly fast, these show that the average lightning speed is considerably slower than the speed of light.

What is faster the speed of lightning or the speed of light?

Light is faster than lightning.


How to write lightning speed in Japanese?

Lightning speed would be "kaminari no hayasa."


What is the wind speed in a lightning storm?

Lightning is caused by a build up of electrical charge in the atmosphere. Wind speed is not connected to the production of lightning. Lightning can occur at any wind speed.


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.


Is lightning or sound faster?

Lightning. Because it is the speed of light.


How is lightning measured?

Lightning is measured depending on the speed of wind it has for example if the speed is 130 mph then the measurement of the lightning will be about only 40 or 50 length


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.


What is the adjective form of lightning?

The noun lightning itself (electrical discharge) is used as a noun adjunct, rather than an adjective, in such terms as lightning bolt or lightning rod. Only when the intent is to show great speed or quickness (lightning speed, lightning reflexes) is lightning an adjective.


What is lightings speed?

The speed at which lightning strikes is the speed at which electrical energy travels. That is the speed of light. So one can say that the lightning's speed is 3*10^8 meters/second. Lightning is usually a mess of electrons traveling. They usually travel much less than the speed of light. The light travels at 3(10^10) cm/s, but the charges themselves travel more slowly.


Can computers process data in a speed of lightning?

no.


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.


Is thunder faster than the speed of light?

Thunder (caused by lightning) is a sound. It travels from the lightning to youat the speed of sound.
