The speed of sound is the distance a sound wave travels through an elastic medium. The speed of sound through air at 20 °C is equal to 343 meters per second, or roughly
767 miles per hour
. Speed of sound can be abbreviated as sound; for example, 1 speed of sound can be written as 1 sound.
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).
Does sound travel at 1 mile per 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).
Does sound travel at 500 miles per hour?
| Miles Per Hour Speed Of Sound | 200 mph 0.260665 sound | 300 mph 0.390997 sound | 400 mph 0.521329 sound | 500 mph 0.651662 sound |

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
.
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 far can sound travel in one hour?
At ~60 degrees Fahrenheit (that’s 15.5 degrees Celsius), the speed of sound is around 760 miles per hour (or
1,225 kilometers per hour
). Note that the sound speed depends on the temperature of the air. That is because in colder air, the air particles move more slowly and thus don’t propagate the sound wave as quickly.
What is the Mach speed of sound?
Near and beyond the speed of sound, about
330 m/s or 760 mph
, small disturbances in the flow are transmitted to other locations isentropically or with constant entropy. But a sharp disturbance generates a shock wave that affects both the lift and drag of an aircraft.
How fast in mph is 10 times the speed of sound?
At this point, the plane’s scramjet engine would fire up and take the aircraft to an unbelievable Mach 10, or just under
8,000 mph
(12,348 km/h).
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 does sound travel every 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.
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 |

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).
Who was the first person to break the sound barrier?
U.S. Air Force Captain
Chuck Yeager
becomes the first person to fly faster than the speed of sound. Yeager, born in Myra, West Virginia, in 1923, was a combat fighter during World War II and flew 64 missions over Europe.
How fast do you have to go to break the sound barrier?
The moment an aircraft’s speed exceeds the speed of sound, it is said to have broken the sound barrier. 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
.
How long does it take for sound to travel 18 miles?
| Speed Of Sound Miles Per Hour | 18 sound 13,811 mph | 19 sound 14,578 mph | 20 sound 15,345 mph | 21 sound 16,113 mph |

How fast can we travel compared to the speed of light?
Nothing can travel faster than
300,000 kilometers per second
(186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It’s impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
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.
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
!
Is sound faster in air or water?
While
sound moves at a much faster speed in the water than in air
, the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.
How fast does sound travel in water miles per hour?

How fast is the speed of dark?
Darkness travels at the speed of light
. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
What is the fastest jet?
The
Lockheed SR-71 Blackbird
is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.
