- The closer you are, the shorter the gap between the lightning and thunder. The speed of sound is around 767 miles per hour (1,230 kilometres per hour). The speed of light is around 669600000 miles per hour (1080000000 kilometres per hour). Thunder is difficult to hear at distances over 12 miles (20 kilometres).

Lightning Lightning starts with an invisible stream called a stepped leader comes out of the cloud. This moves like a step down toward the ground. When the stepped leader is about 300 ft from the ground, lightning shoots up from the ground to meet it in what is called the return stroke.

How fast does lightning strike? It takes the current about 1 microsecond to reach its peak value, which averages around 30,000 amperes. The return stroke produces more than 99% of a lightning bolt's luminosity and is what we see as lightning.

Lightning Most lightning is negative, meaning the ground is more positive. An average bolt of negative lightning carries an electric current of 30,000 amperes (30 kA), and transfers 15 coulombs of electric charge and 500 megajoules of energy. Large bolts of lightning can carry up to 120 kA and 350 coulombs.

Lightning: Just for kids 1 The temperature of a lightning flash is 15,000 to 60,000 degrees Fahrenheit. That's hotter than the surface of the sun (9,000 degrees Fahrenheit). 2  A stroke of lightning moves about 62,000 miles per second--one-third the speed of light.  A single lightning flash carries an electric current as high as 300,000 amperes.

A . Harfield Ltd 1 Each lightning stroke typically lasts only last 10 to 50 microseconds (0.000050 sec) and carries hundreds to thousands of amps. 2  The air around a lightning strike is typically superheated to about 20,000 degrees Celsius or over 3 times hotter than the surface of the sun (estimated at 5,500 C).

Lightning rod A lightning rod (US, AUS) or lightning conductor is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it will preferentially strike the rod and be conducted to ground through a wire, instead of passing through the structure, where it could start a fire or cause electrocution.

How to Estimate Lightning's Distance Normally, thunder can be heard up to 10 miles from the lightning that makes it. Lightning heats the air around it to as much as 60,000 degrees, producing sound waves by the quick expansion of the heated air. Since light travels at 186,000 miles per second, you see the lightning the instant it flashes. But sound, including thunder, travels about a mile in five seconds near the ground. If 15 seconds elapse between seeing a lightning bolt and hearing its thunder, the lightning was about three miles away. Lightning closer than about three miles away is a warning to take shelter immediately.

Lightning Distance Calculator The delay between when you see lightning and when you hear thunder occurs because sound travels much, much slower than light. Sound travels through air at about 1100 to 1200 feet per second (our default is 1150). That is a little more than one mile per five seconds. This approximation will give you a good idea of how far away the lightning was.

How Fast Does Lightning Travel? Quick Answer. Lightning travels at around 220,000 miles per hour when traveling downwards from a cloud, and then reaches a speed of 220,000,000 miles per hour when moving skyward on its return stroke. A flash of lightning is just 1 to 2 inches wide, but it generates a massive amount of electricity that is equal to 300 million volts, or 30,000 amps.

- Paul on Jul 14, 2009. Lightning has been know to move horizontally up to 50 miles from a storm. It has also been known to strike under clear skies. This happens when a thunderstorm is on one side of a mountain and it is clear on the other side.

A . Harfield Ltd 1 The estimated peak power per lightning stroke is 10^12 watts (1,000,000,000,000 watts or 1,000 Giga Watts). 2  The total energy in a large thunderstorm is thought to be enough to power the whole of the USA for 20 minutes.

Information for the Media The average flash will light a 100 watt bulb for more than 3 months. Lightning’s heat exceeds 50,000 degrees F. or three times hotter than the surface of the sun. Its’ speed is 90,000 miles per second (one hundred million feet per second). The average thickness of a bolt is 1-2 inches.

Can you calculate how far away lightning struck by thunder? When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck. If it takes 10 seconds for the thunder to roll in, the lightning struck about 2 miles or 3 kilometers away.

How fast does lightning strike? According to Jerry Dennis, at the American Department of Energy, lightning bolts travel at speeds up to 93,000 miles per second. What we see as a single lightning flash is actually several lightning bolts that follow each other so rapidly that our eyes see only a single flash.t takes the stepped leader about 50 milliseconds (1/20th of a second) to reach its full length, though this number varies depending on the length of its path. Studies of individual strikes have shown that a single leader can be comprised of more than 10,000 steps!

How Lightning Works As you can see, the purpose of the lightning rod is not to attract lightning -- it merely provides a safe option for the lightning strike to choose. This may sound a little picky, but it's not if you consider that the lightning rods only become relevant when a strike occurs or immediately after a strike occurs.he rod might be an inch (2 cm) in diameter. It connects to a huge piece of copper or aluminum wire that's also an inch or so in diameter. The wire is connected to a conductive grid buried in the ground nearby. The purpose of lightning rods is often misunderstood.

Lightning flashes and strokes Most commonly, the lightning current ceases in about a millisecond for a given stroke, but sometimes there is a continuing current on the order of 100 amps following one or more of the strokes. This is called hot lightning and it is the cause of lightning fires according to Uman. The temperatures of lightning are 15,000-60,000°F for both cold and hot lightning - it is the continuing current that starts some 10,000 fires per year in the U.S. in the estimation of Uman.

- The primary purpose of a lightning rod is to. A. attract lightning and guide it to the ground. B. discharge the structure to which it is attached. C. cancel the electric field within the structure to which it is attached. D. induce within the structure to which it is attached a charge opposite to that of charged clouds overhead.

World Lightning Map Enlarge. Lightning is a sudden high-voltage discharge of electricity that occurs within a cloud, between clouds, or between a cloud and the ground. Globally, there are about 40 to 50 flashes of lightning every second or nearly 1.4 billion flashes per year. These electrical discharges are powerful and deadly.
