## How fast is thunder in miles?

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.

## How fast is thunder in miles 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 fast is sound in 5 seconds?

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 fast is the sound of thunder?

Thunder travels at the speed of sound and has a value of about 340 meters per second. The speed of sound in air at sea level moves about 1 mile every 5 seconds.

## How fast does sound travel a mile?

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.

## How fast sound travels a mile?

roughly 5 seconds
The speed of sound changes depending on temperature and humidity but one can estimate that sound travels 1 mile in roughly 5 seconds.

## What are the side effects of getting struck by lightning?

Symptoms of a lightning strike include:

• Thermal burns.
• Clothing that is blown apart or burned.
• Breathing problems, including not breathing.
• Confusion, disorientation, and memory problems.
• Cardiac arrest or irregular heartbeat.
• Personality changes, which can be permanent.
• Loss of consciousness or coma.
• Temporary hearing loss.

## Why a person 1600 meters away hears thunder about 5 seconds after seeing the lightning?

A bolt of lightning heats the air along its path causing it to expand rapidly. Thunder is the sound caused by the rapidly expanding atmosphere. The light and sound actually happen at the same time, but the light of the lightning flash travels faster than the grumbling sound of the thunder.

## What is the 30 30 rule for lightning?

When You See Lightning, Count The Time Until You Hear Thunder. If That Is 30 Seconds Or Less, The Thunderstorm Is Close Enough To Be Dangerous – Seek Shelter (if you can’t see the lightning, just hearing the thunder is a good back-up rule). Wait 30 Minutes Or More After The Lightning Flash Before Leaving Shelter.

## Is lightning hotter than the sun?

Air is a very poor conductor of electricity and gets extremely hot when lightning passes through it. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit (5 times hotter than the surface of the sun).

## Whats faster lightning or sound?

Lightning heats the air and causes shock waves. Lightning and thunder happen at the same time. 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.

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.

344 meters
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 do you know if you’re about to be struck by lightning?

7 Signs That Lightning Is About to Strike

• You See Tall, Bright White Clouds.
• You Can Hear the Thunder Approaching.
• You See Your Hair Standing on End or Feel Tingling.
• You Taste Something Metallic.
• You Smell the Scent of Ozone in the Air.
• You Start to Get Dizzy or Sweat.
• You Can Hear Vibrating, Buzzing, or Crackling.

## How long does it take for the sound of Thunder to travel a mile?

It typically takes the sound of thunder 5 seconds to travel a mile. So, by counting the number of seconds it takes between the flash of lightning and the sound of thunder, you can determine how far you are from the lightning strike.

## How to calculate distance between flash of lightning and sound of Thunder?

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.

## Which is faster the speed of lightning or thunder?

Thunder travels at the speed of sound and has a value of about 340 meters per second. The speed of sound in air at sea level moves about 1 mile every 5 seconds. Thus, when you see the lightning count the seconds and divide by 5 to get the approximate distance that the sound of thunder originates from.

## How long does it take for Lightning to travel a mile?

If you hear the sound of a rumble, lightning is at least several miles away. To calculate the lightning thunder distance, you need to understand the difference between the speed of sound and light. It typically takes the sound of thunder 5 seconds to travel a mile.
