Q & A: The Speed of Lightning | Department of Physics
Oct 22, 2007 · The "leader", the first stroke of a lightning discharge, actually proceeds in steps -- lengthening by about 30 meters at a time, taking about a microsecond (one millionth of a second) to do each step. There is a pause between steps of about 50 microseconds.

Lightning - Wikipedia
Three primary types of lightning are defined by the "starting" and "ending" points of a flash channel. • Intra-cloud (IC) or in-cloud lightning occurs within a single thundercloud unit.• Cloud-to-cloud (CC) or inter-cloud lightning starts and ends between two different "functional" thundercloud units.

How Fast Is Lightning? - Reference.com
Apr 14, 2020 · The return stroke of a lightning bolt travels at approximately 100,000 kilometers per second, which is one-third the speed of light. The characteristics of lightning change slightly with atmospheric variables such as temperature, pressure and humidity.

Lightning Strike - NASA
May 13, 2021 · When lightning strikes, a bright flash of light is generated. Light travels at a constant 186,000 miles/second, which means that we see the flash immediately as it happens. The intense heat of the lightning generates a sound called thunder which is transmitted through the air at the speed of sound. Because the speed of sound is so much slower than the speed of light, we always see the …

How fast does lightning travel? - Quora
The lightning strike itself doesn’t even come close to the speed of light, even its return stroke, which is in most cases the faster stroke, doesn’t go as fast as the speed of light. This makes sense, because lightning isn’t made out of photons like light is, and it is assumed that photons are the only things which can travel at the speed of light.

Severe Weather 101: Lightning Basics
Lightning can occur between opposite charges within the thunderstorm cloud (intra-cloud lightning) or between opposite charges in the cloud and on the ground (cloud-to-ground lightning). Lightning is one of the oldest observed natural phenomena on earth. It can be seen in volcanic eruptions, extremely intense forest fires, surface nuclear ...

How fast does Lightning travel in mph?
Lightning can be described as a massive discharge of electrical energy that can reach the speed of 130,000 mph and can exceed temperatures of 30,000 degrees Celsius. Although we know a lot about this phenomenon, it is still unclear how and why lightning forms.

Is lightning faster than sound?
But you see lightning before you hear thunder because light, which travels a million times faster than sound, arrives almost instantly. Sound, on the other hand, takes about five seconds to travel one mile.

Is lightning faster than wind?
Realistically lightning is faster than wind. Making reference to Sandaime's little footnote about lightning, lightning is practically light, only in the form of electrons. They give off their own light. I'm an absolute naruto-fan. I dislike sasuke. And in saying that I also admit that I can't see any possible way of lightning being slower than wind.

What is the speed of sound when lightning?
It is possible to figure out how far away a lightning strike is with some simple math. Sound travels through air at "the speed of sound.". Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit).
