The return stroke (the current that cause the visible flash) moves upward at a speed of about 320,000,000 ft per second or about 220,000,000 miles per hour (about 1/3 the speed of light). In comparison, the sound of thunder travels at about 1100 ft per second or about
750 miles per hour
.
How far away is lightning in KM?
Calculate the storm distance.
If you want to know approximately how far away is lightning in miles, divide the number of seconds by 5, for kilometers
divide the seconds by 3
.
Which is faster light or lightning?
Comparing it with the average lightning speed,
Light is ~ 675.45 times faster
.
How long is an average bolt of lightning in KM?
Typically, regular lightning flashes measure between just 0.6 miles and 20 miles (
1 and 20 km
) in length. But as increasingly sophisticated mapping techniques have revealed, some truly colossal bolts are crackling above our heads.
How Far Can lightning travel?
Lightning can travel
10 to 12 miles
from a thunderstorm. This is often farther than the sound of thunder travels. That means that if you can hear thunder you are close enough to a storm to be in danger of being struck by lightning. When thunder roars go indoors.
How fast is super man?
But apart from his cosmic strength, how fast is Superman? Superman can travel
186,000 miles per second
, and if needed he can travel at a speed thousand times higher than that. Superman's reaction time is less than 1 attosecond, which is 1×10−18 of a second.
How far is lightning per second?
| 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 |
|---|
How long for the thunder to be heard if it strikes 12 km away from your location?
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
. Divide the number of seconds you count by 5 to get the number of miles.
What is the 30 30 rule for lightning?
Don't forget the 30-30 rule.
After you see lightning, start counting to 30
. If you hear thunder before you reach 30, go indoors. Suspend activities for at least 30 minutes after the last clap of thunder.
Is lightning hotter than the sun?
In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (
5 times hotter than the surface of the sun
). When lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off.
What is the fastest thing in the universe?
Light
travels about 186,270 miles (more than seven times the circumference of Earth) in one second. In modern physics, light is regarded as the fastest thing in the universe, and its velocity in empty space as a fundamental constant of nature.
Is anything faster than light?
Albert Einstein's special theory of relativity famously dictates that
no known object can travel faster than the speed of light in vacuum
, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.
Can lightning power a city?
Lightning is both incredibly powerful and crazy fast. While it's true that
a single lightning bolt could power the entire city of Santa Fe for about a minute
, there are some issues with capturing lightning as an energy source.
How far does lightning travel underwater?
Because seawater is a good conductor, the remaining current penetrates hemispherically downward and fully dissipates less than 10 feet below the surface. It is believed that lethal current spreads horizontally only
20 feet
from the position of strike impact.
Is Dark lightning real?
Dark lightning is the most energetic radiation produced naturally on Earth, but was unknown before 1991
. While scientists now know that dark lightning naturally occurs in thunderstorms, they do not know how frequently these flashes take place or whether visible lightning always accompanies them.
Can lightning travel 50 miles?
That lightning bolt can travel a great distance –
up to 25 miles
– from the storm cloud.
Can lightning strike a car?
According to NBC 12,
a lightning bolt is so powerful that it could actually go through the tires and melt them
. In reality, it's the car's metal cage that protects the occupants, not the tires. Of course, that might not make sense at first, considering metal is a good conductor of electricity.
How Far Can lightning travel horizontally?
Bolt from the blue: A positive lightning bolt which originates within the updraft of the storm, typically 2/3rds of the way up, travels horizontally for
many miles
, then strikes the ground.
What is Flash's fastest speed?
According to The Flash, Allen's top speed is
Mach 3.3
, or 2,532 miles per hour. Barry is more than your average speed demon, too; by tapping into the Speed Force, an extra-dimensional energy source, he can move backwards and forwards in time and even across dimensions.
How fast is Batman?
Batman can run 20 miles at a pace of
4 minutes and 50 seconds per mile
. That works out to be about a 12.4 miles per hour pace.
How fast is Superman compared to Flash?
As for Superman, he's never shown to move at light-speed while running inside a planetary atmosphere. This image should answer your question, though. This scan was taken from Flash v2, #220. Flash states that Superman is moving at
over 2000 miles/sec
, which is also over 120,000 miles/minute, and also 7,200,000 mph.
Which is first thunder or lightning?
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.
Why is lightning so loud?
It's because
the amount of electrical energy that flows from the cloud to the ground is so enormous
: it's like a very big waterfall of electricity. The louder the sound that you hear, the closer you are to the lightning. Light travels through air much faster than sound.
Can you have lightning without thunder?
No, it is not possible to have thunder without lightning
. Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away.
Does counting seconds after lightning work?
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 loud is lightning right next to you?
A clap of thunder typically registers at about
120 dB
in close proximity to the ground stroke. This is 10 times louder than a garbage truck or pneumatic jackhammer drill. By comparison, sitting in front of speakers at a rock concert can expose you to a continuous 120+ dB level.
