How far is the lightning if you hear the thunder clap 9 seconds after you see the lightning?
For example, if you hear the thunder 9 seconds after seeing the flash, the thunderstorm should be about 3 kilometers away from you. If you see a flash and hear a thunder clap almost simultaneously, the storm must be very near you. Seek shelter immediately. Lightning always comes with thunder.
How far away did lightning strike if you hear thunder 5 seconds after you see the spark?
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.
How far away did lightning strike if the thunder is heard 5 seconds after the lightning bolt is seen?
Make it happen: After you see a flash of lightning, count the number of seconds until you hear the thunder. (Use the stop watch or count “One-Mississippi, Two-Mississippi, Three-Mississippi,” etc.) For every 5 seconds the storm is one mile away.
Why is the sound of thunder clap heard a few seconds later after the flash of lightning is seen?[ 2?
Lightning is seen earlier and thunder is heard later because the speed of sound is 330 m/s and the speed of light is 300,000,000 m/s. Light travels faster than a sound. Thus, light from the lightning reaches first to you. The sound from the lightning takes longer to reach and hence heard later.
How far does thunder travel per second?
Lightning travels at the speed of light, about 186,000 miles per second. This means that you see lightning pretty much when it happens. When lightning strikes, a noise is made which we call thunder. Thunder travels much slower, at the speed of sound, about 1088 feet per second.
How far does sound travel per second?
In air at a temperature of 70° F (22.2° C), sound travels at a speed of about 1,129 feet (344 meters) per second, which is roughly equivalent to one-fifth of a mile in one second, or one mile in five seconds (or one kilometer in about three seconds).
How far away is lightning per second?
The Correct Method to Calculate Lightning Distance
| If thunder is heard | The lightning is . . . |
|---|---|
| 5 seconds after a flash | 1 mile away |
| 10 seconds after a flash | 2 miles away |
| 15 seconds after a flash | 3 miles away |
| 20 seconds after a flash | 4 miles away |
Why do we see lightning first and then after sometime hear the sound of thunder?
If we are watching the sky, we see the lightning before we hear the thunder. That is because light travels much faster than sound waves. We can estimate the distance of the lightning by counting how many seconds it takes until we hear the thunder. It takes approximately 5 seconds for the sound to travel 1 mile.
Why is the sound of thunder delayed?
Since light travels faster than sound, the flash of lightning we see before hearing thunder can act as a forewarning, and even tell us how far away the lightning is. If you see a flash of lightning this summer, count the delay till you hear the thunder.
How many seconds after lightning is thunder?
A general rule of thumb to know how far off a bolt of lightning is when you hear 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.
How Far Can lightning be heard?
Thunder, the sound produced by lightning, generally cannot be heard more than about 15 miles from the nearest point of the lightning bolt from you.
How far can sound travel in 3 seconds?
1 kilometer
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.
How long after the flash of lightning is the clap of Thunder?
The clap of thunder was heard 4 seconds after the flash of lightning was seen. If the air temperature was 28°C, how was the lightning? A simple rule of thumb regardless of air temperature is when you see lightning start counting by seconds until you hear the clap of thunder.
What is the approximate distance of the Thunder Cloud from lightning?
Sound produced by a thunderstorm is heard 10 s after the lightning is seen. The approximate distance of the thunder cloud : (Given speed of sound = 340 m s^1 ) Sound produced by a thunderstorm is heard 10 s after the lightning is seen.
How do you calculate the delay between lightning and Thunder?
The delay between when you see lightning and when you hear thunder occurs because sound travels much more slowly than light. Here’s what you do: Let’s say you counted 18 seconds. To find your distance from the lightning in miles, divide 18 by 5 to get 3.6 miles.
How far can Thunder be heard from a lightning strike?
How to Determine Distance between Thunder and Lightning. Thunder can be heard from a distance of approximately 10 miles from the point of the lightning strike. If you can hear the sound of thunder, it’s a warning that you’re within striking distance of the storm.
