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
.
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 fast does sound travel in air miles per hour?
The speed of sound varies depending on the temperature of the air through which the sound moves. 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).
How long does it take for sound 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 it take sound to travel 6 miles?
The speed of sound changes depending on temperature and humidity but one can estimate that sound travels
1 mile in roughly 5 seconds
.
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.
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 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.
How fast is the speed of sound underwater?
Sound travels faster in water than in air. The speed of sound in air under typical conditions is about 343 meters per second, while the speed of sound in water is about
1,480 meters per second
.
How fast is sound in meters per second?
At 0° Centigrade and 1.013 x 10
5
Newtons per square meter (normal atmospheric pressure), the speed of sound is
331.5 meters/sec
, i.e. 1087 ft/sec or 740 miles/hour.
What is the sound speed in air?
speed of sound, speed at which sound waves propagate through different materials. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is
331.29 metres (1,086.9 feet) per second
.
How quickly 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 fast does sound travel through concrete?
| Solid Speed of Sound (m/s) | Longitudal Shear | Concrete 3700 3200 | Constantan 5177 2625 | Copper, annealed 4760 2325 |
|---|
Where does sound travel fastest?
Sound waves can only travel through a solid, liquid or gas medium. They travel fastest
in solids
, then liquids and slowest in gases.
How do sound waves travel through air?
The air is made up of many tiny particles. When sound is created,
the air particles vibrate and collide with each other, causing the vibrations to pass between air particles
. The vibrating particles pass the sound through to a person’s ear and vibrate the ear drum. Light travels much faster than sound through air.
Which room temperature of air does sound travel faster?
Air Density and Temperature
Since sound is more easily transmitted between particles with strong bonds (tight springs), sound travels faster through
denser air
. However, you may have noticed from the table above that sound travels faster in the warmer 40 C air than in the cooler 20 C air.
What’s the furthest sound can travel?
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. This is the most distant sound that has ever been heard in recorded history.
What is the maximum distance sound can travel?
The normal intelligible outdoor range of the male human voice in still air is
180 m (590 ft 6.6 in)
. The silbo, the whistled language of the Spanish-speaking inhabitants of the Canary Island of La Gomera, is intelligible under ideal conditions at 8 km (5 miles).
How far can light travel?
Light dissipating
In fact
there is no known limit
to how far light can travel. However, as you will be aware from observing torch beams or car headlights, there is a limit to the distance over which these are effective sources of illumination. There are two reasons for this.
How fast is sound in 10 seconds?
The speed of sound, in air, is nominally 750mph. This is a simplification, as the actual speed of sound varies with air pressure and temperature. But let’s say 750mph. Therefore distance traveled by sound in 10 seconds is 750/360 miles =
2.083 miles
.
How far does thunder travel per second?
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 far away is a thunderstorm?
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.
