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.

Can you calculate how far away lightning struck by thunder? ­As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use.So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.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.As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use.

A . Harfield Ltd There is estimated to be around 2,000 lightning storm active around the global at one time creating over 100 strikes per second. These thunderstorms generate a potential difference of 200,000 to 500,000 volts between the Earth’s surface and the ionosphere, with a fair weather current of about 2×10-12 amperes/meter2. Data from NASA’s space-based optical sensors revealing the uneven distribution of worldwide lightning strikes.

Lightning Distance Calculator English Lightning Distance Calculator. Here you can calculate the Distance from Lightning from of the speed of the sound. The seconds will be counted from the flash of the lightning till the sound of the thunder. The sounds travel about 1100 to 1200 feet/sec. Here the default will be 1150.

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.

What is the speed of lightning? 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.

Can you calculate how far away lightning struck by thunder? ­As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.

Lightning Distance Calculator Enter the number of seconds from the flash of lightning until you hear the start of the thunder rumble. If you wish, you can adjust the speed of sound to your preferences; however, under most situations, our default should be used. You should not deviate above 1200 or below 1100 feet per second.

Can you calculate how far away lightning struck by thunder? NEXT PAGENEXT. 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).

- 1 Let's say you counted 18 seconds. 2  To find your distance from the lightning in miles, divide 18 by 5 to get 3.6 miles. 3  To find your distance from the lightning in kilometers, divide 18 by 3 to get 6 kilometers.

- Calculating the Distance from Lightning. 1  1. Watch the sky for a flash of lightning. 2  2. Count the number of seconds until you hear thunder. If you have a digital or analog watch, begin timing as soon as you see the lightning and stop as soon as you hear the thunder. 3  3. Calculate the distance from lightning in miles or kilometers.

The Science of Thunder The flash-to-bang method of protection considers the time between seeing lightning to hearing its thunder. Light from lightning travels at the speed of 186,000 miles per second (300,000 km/second), arriving at the observer in about 10 microseconds when the strike point is 1.85 miles (3 km) away.

Sports Injury Statistics Playground, sports, and bicycle-related injuries occur most often among children between ages 5 and 14 years old. The highest rates of injury occur in sports that involve contact and collisions. More severe injuries occur during individual sports and recreational activities. Most organized sports-related injuries (62 percent) occur during practice. Types of sports and recreational activities. Consider these estimated injury statistics for 2009 from the Consumer Product Safety Commission: Basketball.

Understanding Lightning: Thunder If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.

- The flash of light from lightning travels at about 300,000 kilometers per second or 186,000 miles per second. This is why we see it so much sooner than we hear the thunder. If lightning occurs a kilometer away, the light arrives almost immediately (1/300,000 of a second) but it takes sound nearly 3 seconds to arrive.

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.

Thunder Therefore, the lightning is approximately one kilometer distant for every 3 seconds that elapse between the visible flash and the first sound of thunder (or one mile for every 5 seconds). In the same five seconds, the light could have traveled the Lunar distance four times.

Lightning On Earth, the lightning frequency is approximately 40–50 times a second or nearly 1.4 billion flashes per year and the average duration is 30 microseconds. Many factors affect the frequency, distribution, strength and physical properties of a typical lightning flash in a particular region of the world.

How do I tell how far away a thunderstorm is? Strong winds & low-level temperature variations may though alter these values considerably, with values quoted up to 20 km in some cases; lightning at night can be seen up to 100 km away, depending upon your observing location, obstructions etc.

- Positive lightning is particularly dangerous, because it frequently strikes away from the rain core, either ahead or behind the thunderstorm. It can strike as far as 5 or 10 miles (8 or 16 kilometers) from the storm, in areas that most people do not consider to be a lightning-risk area.

Convert Light Years to Miles Light Years. A light year is the distance that light travels in one year. The year used by the International Astronomical Union is 365.25 days. Therefore a light year is exactly 9,460,730,472,580.8 kilometers. A mile is a unit of distance equal to 1.609344 kilometers.

Planning ahead Research has shown that the most successive flashes are within 6 miles, which means that you should have reached a safe place if lightning is less than 6 miles away. However, lightning may strike up to 10 miles away from the parent storm. If someone is struck by lightning, call 911 immediately.
