How long does sound take to travel 1 mile?
Thunder travels much slower, at the speed of sound, about 1088 feet per second. It takes sound about
5 seconds
to travel one mile.
How long does sound take to travel 4 miles?
The speed of sound changes depending on temperature and humidity but one can estimate that sound travels
1 mile in roughly 5 seconds
.
Does sound travel at 1 mile a 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 does sound travel in 2 seconds?
speed = distance/time
If a sound wave were observed to travel a distance of
700 meters
in 2 seconds, then the speed of the wave would be 350 m/s. A slower wave would cover less distance – perhaps 660 meters – in the same time period of 2 seconds and thus have a speed of 330 m/s.
How far away is a sound if it takes 10 seconds to reach you?
| If thunder is heard The lightning is . . . | 10 seconds after a flash 2 miles away | 15 seconds after a flash 3 miles away | 20 seconds after a flash 4 miles away | 25 seconds after a flash 5 miles away |
|---|
How far can sound travel in 5 seconds?
So sound travels 1 kilometer in roughly 3 seconds and
1 mile
in roughly 5 seconds.
Is lightning faster than sound?
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.
At what speed does sound travel?
Sound can travel in air at approximately
332 metres per second
. This is fast but not nearly as fast as light which travels at 300 000 kilometres per second. This difference in speeds enables us to appreciate that sound does take time to travel.
How far is sound in 15 seconds?
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.
What is the speed of sound at 30000 ft?
The speed of sound (Mach 1) varies with altitude and temperature. If an aircraft is travelling at the speed of sound at sea-level then its speed will be 661 knots (760 miles per hour) or if it is travelling at the speed of sound at 30,000 feet then its speed will be
589 knots
(677 miles per hour).
How long does it take for sound to travel around the Earth?
Travelling at the speed of sound (766 miles or 1,233 kilometers per hour), it takes a noise about
4 hours
to cover that distance.
How fast does sound travel through concrete?
| Solid Speed of Sound (m/s) | Longitudal Shear | Concrete 3700 3200 | Constantan 5177 2625 | Copper, annealed 4760 2325 |

How far away is thunder when you hear it?
Thunder can be heard
up to 25 miles
away, and lightning strikes have been documented to occur as far as 25 miles from thunderstorms – known as a “bolt from the blue.” So if you can hear thunder, you're close enough to be hit by lightning, and sheltering indoors or in an enclosed car is your safest bet.
How fast does sound travel every second?
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
(1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.9 s or one mile in 4.7 s.
In which temperature does sound travel fastest?
Does air temperature affect the speed of sound? Kim Strong, a professor of physics at the University of Toronto says the answer is yes, in fact sound travels faster when the air is hotter. At
25 C
, the speed of sound is 1,246 kilometres per hour.
Which medium will sound travels the fastest?
Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through
solids
than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
What is the speed of sound at 10 C?
| Temperature – t – ( o C) Speed of Sound – c – (m/s) | 10 337.4 | 15 340.4 | 20 343.3 | 25 346.3 |

Does every lightning strike hit the ground?
Does lightning strike from the sky down, or the ground up?
The answer is both
. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.
How Far Can lightning be seen?
All lightning comes from a thunderstorm, but you can see that lightning many miles away from a storm when the sky is clear (clear away from the storm, of course). How far? Depending on visibility conditions, you can see lightning from as far as
150 to 200 miles away on a dark summer night
.
How accurate are lightning strike maps?
The detection efficiency (the percentage of the actual strikes that are detected by the network) is reported to be 80%-90%. The reported locations of strikes are accurate
on average to about 0.5 km
.
How many miles per second does light travel?
Light from a moving source also travels at 300,000 km/sec (
186,000 miles/sec
).
How does your brain interpret sound?
The tiny hair cells in our inner ear send electrical signals to the auditory nerve which is connected to the auditory centre of the brain where the electrical impulses are perceived by the brain as sound.
The brain translates the impulses into sounds that we know and understand.
How many kilometers does sound travel in 5 minutes show all your work?
1 Expert Answer
Should be 60 s/min, not 3600, so the end result is
103 km
.
What speed is sonic boom?
Sonic boom is an impulsive noise similar to thunder. It is caused by an object moving faster than sound —
about 750 miles per hour at sea level
. An aircraft traveling through the atmosphere continuously produces air-pressure waves similar to the water waves caused by a ship's bow.
How many Mach is the speed of lightning?
The flash from the lighting that we see moves at the speed of light itself. However, the actual strike itself moves at only 1/3 of lighting, 270,000 mph or
Mach 364
.
What happens to the human body when struck by lightning?
Dr. Griggs says if a person is struck by lightning, it can cause cardiac arrest, which stops a person's body from circulating blood and cause direct injury to the brain and nervous system, preventing the brain from being able to send the appropriate signals to tell the body to continue breathing.
