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.
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.

lightning is able to strike 100 times per second.
i think its 9,000 mph
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.
Lightning speed would be "kaminari no hayasa."
Light is faster than lightning.
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.
Lightning. Because it is the speed of light.
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
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.
Thunder (caused by lightning) is a sound. It travels from the lightning to youat the speed of sound.
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.
At high speed, lightning travels up and down. In result it has a flickering appearence.
A high-speed jet is nowhere near as fast as a lightning bolt.
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
Lightning Speed - 1928 was released on: USA: 26 August 1928 Finland: 3 March 1930
the top speed is 142 miles per hour
The physical manifestation of lightning does not though obviously the light it gives off does.
it might be 100 speed but it depends on what type of lighting it is is it crazy lightning are is is normal lightning and its really cool to see the beautiful colours
The lightning. The speed of light is faster than the speed of sound. In addition, lightning creates thunder, therefore it happens first, therefore must be faster. See the related link for more information.
Light speed is much faster than the speed of sound, ergo the light you see in lightning is visible, before you here the sound.
The speed of light is faster than the speed of sound. So when lightning occurs, you can see it sooner than you then hear it. The further away you are from the lightning, the longer it takes for you to hear it. If lightning occurs right near you, you see the flash and hear the thunder at the same time.
fast like a speed of a lightning
The light from the lightning travels at the speed of light, whereas the sound (thunder) travels much slower.
jay is the ninja of lightning. in the card & spinner game lightning shows how much speed you have.
Because the speed of light is faster than the speed of sound.
