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 at 10 km?
Altitude Speed of Sound | Feet (ft) Meter (m) km/h | 0 (sea level) 0 (sea level) 1,225 | 5,000 1524 1,204 | 10,000 3048 1,182 |

How fast is light in KM?
Light from a stationary source travels at
300,000 km/sec
(186,000 miles/sec).
What is the speed of sound in 1 hour?
In non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or
767 miles per hour
.
How many kilometers does sound travel 4 hours?
The answer you get should be
4939.2 km
.
How fast does sound travel per second?
This method is based on the fact that light travels much faster than sound through the atmosphere: Light travels at 186,291 miles per second (299,800 km/s), whereas the speed of sound is only about
1,088 feet per second
(332 meters per second), depending on air temperature.
Does sound travel at constant speed?
The speed of sound in the atmosphere is a constant that depends on the altitude
, but an aircraft can move through the air at any desired speed. The ratio of the aircraft’s speed to the speed of sound affects the forces on the aircraft.
What is the speed of sound at 85000 feet?
The SR-71 cruised at
Mach 3.2
, more than 2,000 mph, around 85,000 feet.
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 |

Is time Travelling possible?
In Summary:
Yes, time travel is indeed a real thing
. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
How did Einstein find the speed of light?
It can be derived from Maxwell’s equations that the speed at which electromagnetic waves travel is:
c=(ε0μ0)−1/2
. Since light is an electromagnetic wave, that means that the speed of light is equal to the speed of the electromagnetic waves.
Can humans travel at the speed of light?
Can we travel at the speed of light?
No, we cannot travel at the speed of light
. You see, if an object travels at the speed of light, its mass will increase exponentially!
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 you find the speed of sound?
SPEED=DISTANCE/TIME
. To work out the speed of the sound in metres per second, divide the distance in metres by the average time in seconds. For example 170 metres divided by 0.50 seconds = 340 m/s. You have calculated the speed of sound!
Do high frequency sounds travel faster?
Comparing two waves of the same wavelength,
a higher frequency is associated with faster movement
. Comparing two waves of different wavelengths, a higher frequency doesn’t always indicate faster movement, although it can.
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
.
At what temperature will the speed of sound in air be 349 m s?
Answer. At
30 degrees Celsius
, the speed of sound is 349 m/s.
Why does sound travel faster in wood than in water?
Textbook solution. Material medium is a basic requirement for sound wave propagations. The speed of sound depends on the medium through which they travel.
Since the speed of sound is much faster in solids than in liquids
, the speed of sound is more in the wood when compared to water.
How far is lightning from KM?
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
. It will give us 3 miles or 5 kilometers. Or simply use our lightning distance calculator, which can calculate it more accurately at a speed of light!
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
.
Do sound waves travel fastest in solids?
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.
Are shock waves faster than sound?
In particular,
shock waves travel faster than sound
, and their speed increases as the amplitude is raised; but the intensity of a shock wave also decreases faster than does that of a sound wave, because some of the energy of the shock wave is expended to heat the medium in which it travels.
At which temperature will sound waves travel faster?
Temperature of Air Speed of Sound Waves (m/s) | 20 °C 343 | 100 °C 386 |

What is the speed of sound at 70000 feet?
ALTITUDE SPEED OF SOUND | Feet (ft) Meter (m) mph | 10,000 3048 734.5 |

How fast do planes fly?
FAQ » Careers, General FAQs » How fast do commercial planes fly? The average cruising airspeed for a commercial passenger aircraft that flies long distances is approximately
880–926 km/h (475–500 kn; 547–575 mph)
.
What is the sound barrier at sea level?
At what speed do you break the sound barrier? The speed at which you break the sound barrier depends on many conditions, including weather and altitude. It’s approximately 770 mph or
1,239 kmh
at sea level.
