Anonymous users2024-02-07When the air is at 0, the speed of sound propagation is meters and seconds, but a rise in temperature of 1 increases the speed by 60 centimeters: v=, t is the temperature at that time. When the temperature is 15, the propagation speed of sound can be obtained as long as it is 15 generations t.
In other words, at 15 hours, the speed of the sound is meters and seconds (the general speed of the sound is 340 meters at this time). Also, if the air temperature is -20, the speed of the sound is meters and seconds. If you convert the speed of 15 at room temperature to speed, it reaches more than 1200 kilometers per hour, so the speed of sound is very fast.
In addition to the speed of sound, the speed of sound also varies depending on the material being transmitted. In solids, for example, marble is 3,810 m sec and glass is 5,000 m sec. Also, if it is liquid, 15 meters in water for 1430 seconds.
The same sound travels twice as fast in water as it does in air.

Anonymous users2024-02-06The speed at which sound travels through the air is about 340 meters in seconds.
Whereas, the propagation speed in the water is about 1500 meters per second.
The propagation velocity in cork is about.
500m/s
The speed of propagation in kerosene is about.
1324m/s
How so? I always thought that sound travels the fastest in the air!
Why is even cork faster than him? Is there a problem with my data?

Anonymous users2024-02-05The speed of sound in the gas is about several hundred meters per second, which increases with the increase of temperature, and the speed of sound in the air is 331 4 meters and seconds at 0 and 340 meters and seconds at 15, and the speed of sound increases by about 0 6 meters and seconds for every 1 increase in temperature.
The higher the temperature, the faster the propagation.
Then of course, the sound is like a place with high temperatures.

Anonymous users2024-02-04The propagation of sound requires a medium. The speed at which sound travels depends on the temperature and medium. The speed is different at different temperatures and media. Generally we calculate the speed of the sound depends on 340m per second.

Anonymous users2024-02-02The speed at which sound travels through the air is 340 meters per second.
We know from secondary school physics classes that sound travels at a speed of about 340 meters in the air and even faster in solids, such as 18 kilometers per second in diamonds, the hardest substance known on Earth.
The form in which sound travels through the air.
Sound travels in the air as sound waves, and in solids and liquids it also travels as sound waves, but at different speeds. In the air, the propagation of sound is manifested by the oscillation of the air molecules by the sound source, resulting in a certain dense distribution, and this dense distribution is transmitted through the interaction between molecules.
Sound travels through the air in the form of sound waves. The propagation of vibrations produced by sound emitters in the air or other substances is called sound waves. Sound waves travel in all directions with the help of various mediums.
Sound waves are usually longitudinal waves, but also transverse waves, and the propagation of sound waves is essentially the transfer of energy in a medium. Sound waves can be understood as the propagation of small perturbations of a medium that deviates from the equilibrium state.
This propagation process is only the transfer of energy and does not take place the transfer of mass. If the perturbation is relatively small, the propagation of the sound wave satisfies the classical wave equation and is a linear wave. If the disturbance is large, the linear acoustic wave equation is not satisfied, and the dispersion of the wave and the generation of shock waves will occur.

Cork 500m s, less than kerosene (25), distilled water (25), etc.), the speed of sound propagation is related to the type of medium and the temperature of the medium.

The speed of sound is also the speed of sound, which is the speed at which sound travels through a medium. Sound waves can travel in solid, liquid, or gaseous media, and the denser the medium, the faster the speed of sound. In the air, the speed of sound varies depending on the state of the air (e.g., humidity, temperature, density).
Sound propagation process:
When the tuning fork is struck, it vibrates, and this vibration causes the air around the tuning fork to vibrate, and the vibration will travel from the air to the air on the other side, and eventually connect together to form a wave, that is, a sound wave.
If you hit the tuning fork in the darkness of space, because there is no air in space, only the tuning fork is vibrating, so in space, there is no sound.
Vibrations can travel not only in the air, but also in liquids, solids, so we will feel that sound is everywhere on earth. Moreover, due to the difference in gases, liquids, solids, the speed of propagation of sound waves is also different:
Vacuum 0m s (i.e. no propagation).
Air(15)340ms
Air (25) 346m s
Cork 500m s
Kerosene (25) 1324m s
Distilled bright distilled water (25) 1497ms
Seawater (25) 1531m s
Copper (rod) 3750m s
Marble 3810m s
Aluminum (bar) 5000m s
Iron (rod) 5200m s

Anonymous users2024-01-29The speed of sound is about 340 m/s at standard atmospheric pressure.
The magnitude of the speed of sound varies depending on the nature and state of the medium. Generally speaking, the value of the speed of sound is greater in solids than in liquids, and in liquids it is greater than in gases. The speed of sound in the air is about 340 meters and seconds, or 1224 kmh, under standard atmospheric pressure conditions.
The magnitude of the speed of sound also varies with the temperature of the atmosphere, and in the troposphere, as the altitude increases, the air temperature decreases and the speed of sound decreases. In the lower stratosphere, the air temperature does not change with altitude, and the speed of sound does not change, which is meters and seconds. The law of air flow and the aerodynamic characteristics of the aircraft have a huge difference between the flight speed less than the speed of sound and the speed of sound, so the speed of sound is a very important benchmark value for studying the movement of aircraft in the atmosphere.
Influencing factors: The sound waves emitted from the sound source propagate to the surroundings at a certain velocity, which means that the energy of the sound waves also propagate to the surroundings at a certain velocity. As far as is known, sound waves are capable of propagating in all matter except vacuum.
Its propagation speed is determined by certain physical properties of the sound transmission medium, mainly mechanical properties.
For example, the speed of sound is related to the density and elastic properties of the medium, so it also varies with state parameters such as temperature, pressure, etc. of the medium. The speed of sound in the gas is about several hundred meters per second and increases with increasing temperature, the speed of sound in the air is about milliseconds at 0 and 340 meters at 15, and the speed of sound increases by about milliseconds for every 1 increase in temperature.
In general, the speed of sound is greatest in solid media, less in liquid media, and smallest in gaseous media. In addition, the speed of sound in an inhomogeneous medium varies everywhere. The speed of sound in an anisotropic medium varies with the direction of propagation.
The speed at which sound travels through the air is 340m s. 1. What factors are related to the propagation speed: the speed of sound propagation in the air is related to the density of the obstructing object, because the propagation of sound is easy to be obstructed or absorbed, first of all, the dense object is easy to block the sound and reflect the sound back, so that a reflection will make the speed smaller, and the low density will easily let the sound penetrate the past part, so that the speed is also changed; Absorption means that there is a possibility that the sound energy will decrease during the propagation process, and the decrease of sound energy will make the speed of sound. >>>More

Although the propagation speed of light in a vacuum is the same, due to the different wavelengths and frequencies of different color light, the refractive index of different colors of light in the medium is different, the refractive index is denoted by n, the speed in the medium is set to v, and the speed in the vacuum is c, n=c v, according to which the speed of different colors of light in different media can be deduced.
The adsl we use here is up to 8M, but it is generally on 2M broadband, so the speed is about the same as you said, in fact, the reason why we are slow, the main reason is that we open the upload speed is slow. If it's faster, it should be faster. This is relative.
