Blame!! The speed of light is fast?? Fast speed of sound??

This is the problem of picture and sound synchronization in TV signal transmission, when TV signal transmission, the transmitting terminal decomposes the signal collected by the camera into picture signal and audio signal, and then broadcasts it through satellite, and the ground receiving station will receive the signal for merger processing, but the information amount of the general picture signal is much greater than the information amount of the audio signal, so in general, the transmission of the picture is always a little slower than the audio.

Generally, when the signal quality is very good, the delay difference between the two is very small, and it is generally difficult to feel it.

When the signal quality is not good, the transmission delay time of the picture signal is larger than that of the audio signal, so there will be a situation where the picture and the sound are not synchronized, so there will be a situation where we have heard the sound, but the picture we see is one beat slower than the sound

At present, the weather and geographical conditions in the disaster area are complicated, and the transmission of satellite signals is easily interfered with, so the on-site pictures in the past few days are somewhat incorrect

It's caused by the fact that the TV station or the TV you watch doesn't adjust the sound signal and the image signal to propagate consistently.

Hehe, it's not because the speed of sound is faster than the speed of light, thank you.

Well, I guess they probably didn't match the lip sync. Normally, the speed of light is several times the speed of sound.

Miscellaneous, the transmission of satellite signals is easy to receive interference, so the live pictures in the past few days are somewhat incorrect

Is it that complicated? What do you use, is it a computer? The computer may be stuck haha.

The speed of light is faster than the speed of sound. Vacuum speed of light definition value: c0=299792458m s; The speed of sound in the air is about 1 m second at 15 standard atmospheres and 340 m seconds.

The speed of light in a vacuum is the maximum speed at which an object moves in nature. The speed of light is independent of the speed at which the observer is moving relative to the light source. The mass of the object will increase with the velocity, and when the velocity of the object approaches the speed of light, its moving mass will tend to infinity, so it is impossible for an object with a mass of non-0 to reach the speed of light.

Only photons with zero static mass are always moving at the speed of light.

Answer: The speed of light is faster than the speed of sound.

The propagation velocity of light in vacuum and air is 3x10 8ms, and the propagation speed of sound in air is 340ms

The speed of light is much greater than the speed of sound.

The speed of light is fast, 3x10 8m s

Speed of sound: The speed at which sound travels in different media:

Vacuum 0m s (i.e. no propagation).

Air (15) 340m s

Air(25) 346m s

Cork 500m s

Kerosene (25) 1324m s

Distilled water (25) 1497 ms

Seawater (25) 1531m s

Copper (rod) 3750m s

Marble 3810m s

Aluminum (rod) 5000m s

Iron (rod) 5200m s

Which is faster, the speed of light or the speed of sound, and how fast?

The speed of light is fast, the speed of light is the fastest propagating substance in the universe, the internationally recognized value of the propagation speed of light in a vacuum is c = , while the speed of light in water is 3 4 c and the speed in glass is 2 3 c. The speed of sound travels at different speeds in different media (sound propagation requires matter, which is called a medium in physics), and I have given some examples below: (unit:

m s) Air(0) 331 Air(15) 340 Air(25) 346 Cork 500 Kerosene (25) 1324 Water (room temperature) 1500 Seawater(25) 1531 Ice 3230 Copper (rod) 3750 Marble 3810 Aluminum (rod) 5000 Iron (rod) 5200 Note: Sound cannot travel in a vacuum. Hope to adopt.

The speed of light or the speed of sound, which is faster.

The speed of light is faster than the speed of sound. The definition of the speed of light in a vacuum: c0 = 299792458m s, the speed of sound in the air is about 340m seconds at 1 standard atmosphere and 15 m s.

The speed of light velocity of light in a vacuum is the maximum speed at which an object in nature can move. The speed of light is independent of the speed at which the observer is moving relative to the light source. The mass of the object will increase as the velocity increases, and as the velocity of the object approaches the speed of light, its kinetic mass will be.

The speed of light is fast??

The speed of light, light in a vacuum (3 10 8 m sec), while sound transmission requires a medium: air (340 m s).

The speed of light is 3 times 10 by 8 of this square.

The speed of sound in air is 340m s

The speed of light (300,000 km/s) is much greater than the speed of sound (340 m/s).

The speed of light is fast??

According to the theory of relativity, the speed of light is the fastest in nature, reaching 3 10 8m s

The speed of sound is only 340m s, which is much less than the speed of light.

In the existing research phase, the speed of light is greater than the speed of sound.

Of course, the speed of light is the first to see lightning before hearing thunder.

Is the speed of light fast or the speed of sound? - The speed of light, of course

V light in air = 300000000 m s

V sound = 340m s

It must be the speed of light! The speed of light is 300000000 meters per second, while the speed of sound under normal temperature and pressure of air is 340 meters per second, but the speed of propagation of sound is related to the nature of the medium (air is also a medium, it is a gaseous medium, other media such as steel, solid medium, water, liquid medium, etc.). In general, the speed of sound travels faster in solids than liquids, and liquids are greater than gases.

Specific things need to be analyzed on a case-by-case basis. Each of the different mediums has a different speed of propagation. But the speed of light is much faster than the speed of sound.

Even when the speed of light can be seen with the naked eye, the minimum speed of light is still very fast.

Of course, it is the speed of light, which is 300,000 kilometers per second.

The speed of sound is 340 meters per second (for example, if you see lightning, it will take more than ten seconds to hear thunder, indicating that light travels faster than sound).

Which one do you say is fast?

Don't say that about the landlord... It's a good thing for people to ask Sun Yat-sen once said, "If you don't understand, you don't understand, if you don't understand, you have to ask."

The speed of light is 299,792,458 ms per second.

The speed of sound is 340 m s, which is a big difference!!

The landlord is talking nonsense. The speed of light, of course.

Have you ever heard of a supersonic plane, have you ever heard of a faster-than-light aircraft? If there were such airplanes, they would have flown to ancient times.

Speed of light: 299792458m s (in vacuum).

Speed of sound: The medium required for sound propagation, the speed of sound is affected by the density of the medium of propagation, which is about 340 m s under standard atmospheric pressure conditions.

With these two data, it is not difficult to distinguish.

Sound propagation requires medium, the speed of propagation in different media is not the same, upstairs said that 340m s is propagated in the air, for example, the speed of sound propagation in steel with longitudinal waves is 5900m s, its speed is much faster than in the air, of course, now we know all the objects have not yet reached the speed of sound propagation in it exceeds the speed of light, but it cannot be said that there is no discovery, this problem is not that naïve, but a little profound!

The speed of light is fast, 30,000 kilometers per second and 340 meters per second of sound.

The speed of light is 300,000 kilometers per second in a vacuum, and the speed of sound in 20 degrees of air is 340 meters per second.

The speed of light, of course.

is c=299792458m s=

The speed of sound is only 340m s

You can think about it.

When there is thunder.

It was the first to see the lightning or the first to hear the thunder. You'll know when you understand this.

The speed of light, of course.

The speed of light is three times ten to the eighth power of meters per second, while the speed of sound is three hundred and forty-three meters per second.

The speed of light is about 3x100000000m s, and the speed of sound in air is about 340m s

The fastest speed in the world is the speed of light, 300,000 kilometers per second.

When the volume is the same on the ground, is it the iron ball that falls faster or the foam ball that falls faster?

Another child... Nowadays, children can play with the computer, and it will not be such a simple problem...

Upstairs, the speed of sound is 340m s at 15 degrees....This amount is generally used!

Look at the thunder and lightning to know how slow the sound travels.

The landlord's problem is terrible.

Hear it first, then see its people.

1. All the speed of light, the speed of sound, the speed of wind.

Speed of light: 3x10 8 m-s (vacuum), speed of sound: 340 m-s (15 degrees in air, 3 m-s for every 5 degrees of increase) Wind speed depends on the progression.

The speed of light is the fastest - 3000000000 meters per second, the speed of sound is 340, and the wind speed is smaller than the speed of sound.

As we all know, the speed of light is much faster than the speed of sound, for example, when thunder and lightning weather, we see lightning first, and then we hear thunder, so have you ever thought that if the speed of sound is faster than the speed of light, what will happen to the world?

The speed of light is 300,000 kilometers per second, and there is a vacuum! The speed of sound is 343 meters per second, the speed of water is 1460 meters per second, and the vacuum cannot be transmitted!

The premise is in what medium.

In the present life.

The speed of light is definitely greater than the speed of sound.

But if the medium is different.

The speed of sound may be greater than the speed of light.

The speed of light, when it rains and thunders, the lightning you see first or the thunder you hear first.

Of course, it is the speed of light, 300,000 kilometers per second, and the speed of sound is only a few hundred meters per second.

No matter what medium it is, the speed of light is fast.

From a physical point of view, of course, the speed of light is fast.

The speed of light is kilometers per second, and the speed of sound is 340 meters per second. The velocity is also different in different media.

The speed of light is fast, you can experiment, two people are 100 meters apart, shouting a bang.

Lightning is seen first, then thunder is heard. Which one do you say is fast?
