Sound is a sensation created in the human brain in response to sensory inputs from the inner ear. The speed of sound through the atmosphere is a constant that depends on the daily temperature. On a standard day at sea level static conditions, the speed of sound is about 760 mph, or
1100 feet/second
.
How fast does sound travel per second?
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.
Does sound move a 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 long does it take for sound to travel 3 miles?
The speed of sound changes depending on temperature and humidity but one can estimate that sound travels
1 mile in roughly 5 seconds
.
How far can sound travel in 10 seconds?
Therefore distance traveled by sound in 10 seconds is 750/360 miles =
2.083 miles
.
How far can sound travel in 7 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.
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.
How fast is a flash of lightning?
1. The speed of lightning. While the flashes we see as a result of a lightning strike travel at the speed of light (670,000,000 mph) an actual lightning strike travels at a comparatively gentle
270,000 mph
.
How far will a sound wave 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 fast does sound travel per minute?
On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is
761.2 mph (1,225 km/h)
. Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air.
What is the speed of sound in 1 minute?
Speed of sound in the air. But this speed varies between
295-340 m/s
depending on the air temperature and pressure.
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).
What happens when you break the sound barrier?
As this wave-front passes an individual,
the sudden pressure differential or change in pressure creates the “sonic boom” that we hear
. Anything exceeding the speed of sound creates a “sonic boom”, not just airplanes. An airplane, a bullet, or the tip of a bullwhip can create this effect; they all produce a crack.
How fast can sound travel 10 miles?
| Speed Of Sound Miles Per Hour | 8 sound 6,138 mph | 9 sound 6,905 mph | 10 sound 7,673 mph | 11 sound 8,440 mph |
|---|
What is the exact speed of sound?
If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about
761 mph
, or 1100 feet/second. We can use this knowledge to approximately determine how far away a lightning strike has occurred.
How fast does sound travel in millisecond?
| Temperature of air in °C Speed of sound c in m/s Time per 1 m Δ t in ms/m | +20 343.2 2.912 | +15 340.3 2.937 | +10 337.3 2.963 | +5 334.3 2.990 |
|---|
How far away is a thunderstorm?
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 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.
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.
Does bullet travel faster than sound?
When bullets fly through the air, they do so at amazing speeds. The fastest bullets travel more than 2,600 feet per second. That’s equivalent to over 1,800 miles per hour. To put that in perspective, it’s amazing to realize that
bullets travel over twice the speed of sound
!
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.
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.
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.
Is it safe to shower during a lightning storm?
Lightning can travel through plumbing. It is best to avoid all water during a lightning storm.
Do not shower, bathe, wash dishes, or wash your hands
.
