Speed of Sound

Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.

Obtain a bell jar with a valve at the top, place the bell jar on a smooth flat surface. connect the valve to a vacuum pump through a rigid hose. Place a manual wind up spring alarm clock under the bell jar. Seal the bottom lip of the bell jar with petroleum jelly and ensure there are no gaps between the bell jar and the surface. Note the ticking of the clock. Start the vacuum pump and observe when the internal pressure begins to drop. Stop the vacuum pump and close the valve. Listen to the clocks ticking. Re start the vacuum pump and note the pressure drop, close the valve and listen to the ticking clock. As the pressure decreases the sounds of the clock will get fainter and fainter because there is less of the material medium (Air) to transfer the sound.

What a good question, the fastest thing in the world besides light is the space shuttle. But again what a really good question.

Tachyon is believed to be faster than light and as fast as light in its lowest possible velocity.

The speed of sound in soil can vary depending on factors such as soil type, moisture content, and compaction. Generally, it ranges from 300 to 1500 meters per second.

i really dont know lol

That all depends on the frequency of the sound and its speed in whatever substance

it happens to be traveling through.

In air, the wavelength of audible frequencies ranges from about 17.1 millimeters to

about 17.1 meters.

(20-20K Hz, 343 m/s)

Because of their density, sound waves in the air travel more quickly through the solid and liquid mediums. The energy of a compression wave (such as a sound wave) must pass from atom to atom, which makes the more tightly packed atoms of non-gascious mediums more efficient in transferring sound.

You hear a BIG boom when, it comes into your hearing distance, and yes I am only 13.

You do indeed: it's called a "sonic boom" or "breaking the sound barrier". It occurs when the object accelerates through a pressure-wave built up in the air ahead of it by its motion

Moving at 5 times the speed of sound means traveling at Mach 5, which is approximately 3837 miles per hour (6176 kilometers per hour) at sea level. This speed is commonly associated with hypersonic travel and is much faster than typical commercial aircraft speeds.

Sound travels at different speeds depending on the medium it is traveling through. In air at room temperature, sound travels at approximately 343 meters per second. In water, sound travels faster at around 1,480 meters per second. In steel, sound can travel even faster at about 5,960 meters per second.

The frequency of the sound wave gives rise to the perception of pitch. Pitch is synonymous to frequency (which is the number of complete waves, or cycles, per second). The higher the frequency, the higher the pitch, and vice versa. Pitch

The speed of sound is greater in stone than in water or air because sound travels faster in denser materials. Stone is more dense than water or air, allowing sound waves to propagate more quickly through its structure.

On the medium it is travelling in, or more precisely, the distance between particles of a medium :

-Solid : Particles leave almost no space in between, so sound travel faster than liquid and air.

-Liquid : Less close than the solid particles and more close than those of air, so sound travel faster than in air and slower than in solid.

-Air : Gas particles are waaay far of each other and thus sound travels slowest in it.

The formula to calculate wavelength is wavelength = speed of sound / frequency. Plugging in the values, we get wavelength = 1430 m/s / 286 Hz = 5 meters. Therefore, the wavelength of the sound wave traveling through water is 5 meters.

Astronomers don't use the speed of sound as a basis for measuring distances for a number of reason, but mainly because the distances being measured are quite large. The speed of light (300000000 m/s) is about six times faster than the speed of sound (~343 m/s), making it a better unit of measure.

Consider this: Alpha Centauri A and B, which is the closest star system to us, are about 4.1154e+16 meters away. In light years, this is equal to about 4.35 light years away. If you were to measure this distance by using a unit of measure based on the distanced travelled by the speed of sound in one year, it would be equal to about 3.80e+6 "sound years".

To calculate the wavelength of the musical note, you can use the formula: wavelength = speed of sound / frequency. Plugging in the values gives: wavelength = 345 m/s / 26.6 Hz = 12.97 meters. So, the wavelength of the musical note is approximately 12.97 meters.

The speed of sound c in air under normal conditions is only dependent on the temperature. It is independent of the air pressure p.
Reason: The air pressure p and the air density rho are proportional to each other at the same temperature. Hence, the speed of sound in air, which depends on the ratio of p to rho, is constant. Therefore the speed of sound in air is the same on a mountain peak as it is at sea level, provided that the temperature is the same.

On the other hand, if you change from one gas to another, the speed will depend on density. For example, Argon gas and Helium gas at the same temperature and pressure will have very different densities and this will result in very different speeds for sound. In that case, the speed of sound is proportional to the inverse of the square root of the molecular mass. For more details see the related links.

The speed of sound in solids will be much faster than in a liquid, but there is no simple relationship to the density in that case. For example, iron and aluminum have very different densities, but almost the same speed for sound.

If you mean 'after the splash is seen' then g has nothing to do with this problem; only the speed of sound and the distance.

500/340 =1.47 seconds.

If you want to include the time it takes for the stone to fall then

500 = 1/2x10 t2 t= 10 seconds 10+1.47 = 11.47 seconds

SONAR is an application based on the speed of sound. Sound waves are emitted, they bounce off object and some are captured by a receiver. The time taken between emitting the sound and receiving it, multiplied by the speed of sound in that medium, gives the distance that the sound has travelled. The distance to the object can therefore be calculated. If two or three receivers are used then the location of the object can be identified in a 2-dimensional plane or 3-d space.

Some species of bats, whales, dolphins are examples of animals that use echo-location.

To find the wavelength, you can use the formula: wavelength = speed of sound / frequency. Plugging in the values, wavelength = 1430 m/s / 286 Hz = 5 meters. Therefore, the wavelength of the sound traveling through the water is 5 meters.

The speed of sound in water is greater than the speed of sound in air .

For example, at 20 °C and 1 ATM pressure, the speed of sound in air is 343 m/s, and its speed in water is 1482 m/s.

In general, the

speed of sound in a medium = (bulk modulus of the medium/ its density)^0.5

where the bulk modulus indicates how compressible the medium is; the greater the bulk modulus, the more incompressible the medium is.

So,

although water has a density much greater than that of air, water is also much more incompressible than air.

When you solve for the speed of sound for both water and air using the above formula, you will find that it is greater in water.

The speed of sound in air at room temperature is approximately 343 meters per second. The closest thing to this speed that humans can achieve is the speed of a bullet fired from a high-powered rifle, which can travel at speeds up to around 1000 meters per second.

Sound travels through iron at a speed of approximately 5120 meters per second.
