What is the speed of sound in miles an hour?
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.
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.
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.
The speed of sound is 740 mph when the air temperature is 32 degrees. A general rule is that sound travels one mile in 5 seconds at sea level. Light travels at 186,000 miles per second, a speed so great that, for practical use, it can be considered to be instantaneous.
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).
Light from a moving source also travels at 300,000 km/sec (186,000 miles/sec).
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!
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.
Speed of Light (c):
That works out to 299,792,458 m/s, or about 670,616,629 mph (miles per hour).
The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space.
What's faster than speed of sound?
Yes, wind can travel faster than the speed of sound. Wind is just the bulk movement of a mass of air through space and is in principle no different from a train speeding along or a comet zipping through space.
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.
The speed of the sound at this temperature is 352 m/s.

Two of the planes are designed to attain speeds of 1,980 miles an hour—three times the speed of sound which is 660 m.p.h. at 35,000 feet.
How fast is the speed of darkness? Strictly speaking, dark is simply the absence of light, and thus has no speed at all, according to noted astrophysicist Neil deGrasse Tyson.
Ergo, light is made of electromagnetic waves and it travels at that speed, because that is exactly how quickly waves of electricity and magnetism travel through space.
One light year is 5.88 trillion miles.
In the 17th century, the French scientist and philosopher Pierre Gassendi made the earliest known attempt at measuring the speed of sound in air.
What type of wave is sound?
Longitudinal waves
A longitudinal wave is one where all the particles of the medium (such as gas, liquid or solid) vibrate in the same direction as the wave. Sound waves are longitudinal waves. When longitudinal waves travel through any given medium, they also include compressions and rarefactions.
Sound intensity can be found from the following equation: I=Δp22ρvw. Δ p – change in pressure, or amplitude ρ – density of the material the sound is traveling through vw– speed of observed sound. The larger your sound wave oscillation, the more intense your sound will be.
The speed of sound in water is 1480 metres per second.
Sound travels faster in water compared with air because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster.
The speed of sound in solid is 6000 m/s, while the speed of sound in steel is 5100 m/s. Another fascinating finding about sound speed is that sound moves 35 times faster in diamonds than in air.
Speed of light in air is 3×108 m/s and speed of light in common glass is 2*10^8 m/s. Calculate the refractive index of glass. Answer: The glass refractive index is defined as the ratio between the speed of light in the vacuum and the speed of light in the glass.
How many meters in a mile 1 mile is equal to 1,609.344 meters, which is the conversion factor from miles to meters.
Solids, liquids, and gases all transmit sound as energy waves. Sound energy is the result when a force, either sound or pressure, makes an object or substance vibrate. That energy moves through the substance in waves. Those sound waves are called kinetic mechanical energy.
Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.
Sound waves are invisible to our eyes; unless we find a way to make the sound waves move something that we can see.
Does light have sound?
Light does not produce sound because it is not a vibration on a material.

Actually, so long as you aren't travelling with your head sticking out of the plane (which would be a very bad idea), you can hear just fine. This is because the air in the plane is moving with you. The speed of sound is actually the speed that soundwaves travel with respect to the air.
Of course, light travels faster than wind currents , as nothing in this world can travel faster than the light. Speed of light is 3×10^8 m/s..
The speed of sound in air is about 332 meter per second.
The speed of sound in air is 343ms−1.

| 10 sound | 7,673 mph |
| 11 sound | 8,440 mph |
Sound consists of a waveform moving through a material. The speed of sound in a gas is primarily a function of the temperature of the gas. Since air is a mixture of gases and includes water vapor, the relative humidity of air has a slight effect on the speed of sound.

Is Traveling At Light Speed Possible? | Mach | NBC News - YouTube
How fast is the speed of darkness? Strictly speaking, dark is simply the absence of light, and thus has no speed at all, according to noted astrophysicist Neil deGrasse Tyson.
By definition, at Mach 1, the local flow velocity u is equal to the speed of sound. At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic).
Albert Einstein's special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.
Flash was travelling at - 1750000000000000000 / 186000 = 9400000000000 times the speed of light. Which is 9,400,000 million times the speed of light."
Ergo, light is made of electromagnetic waves and it travels at that speed, because that is exactly how quickly waves of electricity and magnetism travel through space.
A Mach number is the ratio of an object's speed in a given medium to the speed of sound in that medium. Mach 1, then, is the speed of sound, around 761 mph at sea level on a standard day. The term is also used as a metaphor for high speeds more generally.
| Speed Of Light | Mach Number |
|---|---|
| 0.001 c | 874.03 M |
| 0.01 c | 8,740 M |
| 0.1 c | 87,403 M |
| 1 c | 874,030 M |
What is the highest Mach speed?
Guinness World Records recognized NASA's X-43A scramjet with a new world speed record for a jet-powered aircraft - Mach 9.6, or nearly 7,000 mph.
This is a little hard to wrap your head around, but shadows can move faster than the speed of light, even though nothing can move faster than the speed of light.
But there is also light, and light will always be stronger than darkness.
No, darkness is not light, as an object which does not emit or reflect energy is truly 'dark. ' Darkness is light radiation which is in thermal equilibrium with its environment. (It would be fair to say, by this definition, that the interior of the sun is dark.)
