The lightning is too far away, the sound receives many obstacles along the way, the sound is greatly weakened, it mostly depends on the medium of air, and the light can travel in a vacuum, so the sound disappears, and the light remains. That's why sometimes you only see lightning on the ground and don't hear thunder!
-
Because the speed of light travels much faster than sound, sometimes you see lightning but you can't hear it because it's too far away from you. The sound has been attenuated.
There's also a very simple formula for figuring out how far away you are from where the flash is.
s (t thunder t lightning) * 340
s represents distance t stands for time unit meter and speed of sound 340m s
-
Because some lightning strikes are so far away from the observer that the sound has been greatly attenuated, the light emitted by the lightning can be seen but the thunder cannot be heard.
-
The correct answer is that lightning can penetrate the clouds to reach the observer's eye in this kind of weather, and sound is greatly attenuated by the various particles in the air and the resistance of the air itself, and the propagation of sound is largely dependent on this medium of air, while light can propagate in a vacuum.
-
Because light not only runs faster than sound, but also farther than sound. Generally speaking, thunder can only go twenty or thirty kilometers. If the place of thunder is too far away from us. We can only see lightning, not thunder.
-
How fast is the speed of light, is the speed of sound as fast as the speed of light? When you see lightning, the sound has not yet reached your ears, or when the light can reach your ears, and the sound has weakened and disappeared due to various resistances
-
Because the speed of light is faster than the speed of sound, sound is already greatly attenuated in propagation!
-
The simple reason is that you're too far away from it ......
-
The lightning is too far away from you.
-
Ask questions like this and you can go back to elementary school.
-
The third reason is that lightning is actually below the horizon, because most of the light is propagating the earth's gravitational pull in a straight line, and there is no way to make them turn. So most of them have escaped from our business, and the sound has reached our ears through different media.
-
Obscured by the clouds. When the clouds are very thick, they can block the light of lightning, and sometimes you can't see lightning, only thunder can be heard.
-
If it's during the daytime, there will be lightning before the rain, but it can't be seen during the day, most of the lightning will be before the rain, and there are very few times when there is no lightning.
-
Because lightning only forms and disappears in an instant. I didn't see the lightning, probably because I missed it. But as long as there are no anomalies, the sound is audible.
-
That means that the thunder is far away from us, and that place can be seen, or the clouds are too thick for us to see the thunder, but the sound can be heard.

<> "Normally, during a thunderstorm, lightning is always accompanied by thunder, but sometimes people only see lightning but don't hear thunder. How does this happen?
Thunder and lightning is a majestic and somewhat intimidating electrical discharge phenomenon accompanied by lightning and thunder. Thunder and lightning are usually generated in the middle of cumulonimbus clouds with strong convection, so they are often accompanied by strong gusts of wind and heavy rain, sometimes hail and tornadoes. The top of the cumulonimbus cloud is generally high, up to 20 km, and the upper part of the cloud often has ice crystals.
Processes such as the attachment of ice crystals, the breaking of water droplets, and the convection of air cause electric charges to be generated in the clouds.
The speed of sound in the air increases as the temperature rises, and sound travels faster in warmer air than in colder air. If the temperature is decreasing upwards, then the upper part of the sound wave traveling horizontally will travel more slowly than the lower part, so the path of the sound wave will bend upward.
Since the temperature is warmer near the ground and colder the upwards, the refraction of sound causes the sound to bend upwards and therefore cannot travel very far along the ground.
On the contrary, the sound waves of thunder are refracted upward by the warmer air near the ground, over a range of more than 25 kilometers, and because the refraction of the sound is very strong, it travels upwards so that people on the ground can only see lightning and cannot hear thunder.
The temperature of lightning ranges from 17,000 degrees Celsius to 28,000 degrees Celsius, which is equal to 3.5 times the surface temperature of the sun. The extreme heat of the lightning caused the air to expand violently along its path. The air moves quickly, so waves are formed and sound is made.
-
In fact, the sound and light produced during thunder are produced at the same time.
Generally, the place where thunder occurs is a certain distance away from you, when the thunder and lightning that occur have to be transmitted to you through space, lightning is light, and the propagation speed of light is 300,000 kilometers per second, while the propagation speed of sound is only 340 meters per second. Light travels much faster than sound, so lightning is seen first, and sound is heard later. Sometimes because the thunder is too far away, the sound is attenuated in the propagation, and the farther the propagation, the more attenuation, so the sound will be too small to be heard.
-
Lightning and thunder are actually a form of atmospheric discharge. Clouds with different charges are placed close to each other, and electrical discharges occur.
Arcs and loud sounds are generated, arcs are what we usually call lightning, and loud sounds are thunder. Both occur at the same time. But since the speed of light is much greater than the speed of sound, and in the air.
-
Because the speed of light is faster than the speed of sound, it will be when you are farther away.
-
Seeing lightning belongs to light, and the speed of light propagation is greater than the speed of thunder (sound), so see lightning first. Whereas, sound (sound waves) travel through the air, and if the energy is less, the sound cannot be heard.
-
Why do you see lightning before you hear thunder? That's because the speed of light travels faster than the speed of sound.
-
1. Lightning and thunder are actually a form of atmospheric discharge. Clouds with different charges are placed close to each other, and electrical discharges occur. An electric arc is what is commonly referred to as lightning, and a loud sound is thunder. Both occur at the same time.
2. But since the speed of light is much greater than the speed of sound, and in the air,. So it's common to see lightning first and hear thunder. The attenuation of sound is greater than that of light, so sometimes only lightning can be seen, but thunder cannot be heard.
Ball lightning remains a mystery to this day.
Reasons for slowing down internet speeds:
1.Rubbing the network: generally using wired Internet computers will not encounter this situation, but with the popularity of notebooks, more and more people take wireless as a way to network, but wireless has a big disadvantage is that it is easy to be rubbed against the network, once it is rubbed against the network, their network speed will naturally slow down, after all, the bandwidth is limited, others use more, and there is less for themselves. >>>More
Although it is the world of science, sometimes you really have to believe in fate, of course, it does not mean that you have to be unlucky all the time, a person's mentality can move fate. It's a bit empty. In short, try to tell yourself first, there is something good this month, and then remind yourself every day, then the bad luck is far away, very smart, when I was in school, my classmates called "moldy god", there is no bad luck that I can't meet, but the more negative the luck, the worse the luck, or positive to face it.
It shows that you are a sentimental and sentimental person. The little suffering, sadness, happiness, sadness, and worry in your past life are your sentimentality; When the same, similar, and similar situations that you think are worth remembering but refuse to forget, you are immersed in the complex emotions of the present and the past, which are your good feelings. It's not a bad thing to be so sentimental and have a really red feeling, it's better than losing your temper; It's just that you can't be overjoyed and compassionate, and proper sadness and sadness are not harmful to the body (if you want to cry, cry out, don't hold back, it's not good for the body). >>>More
You're still young, right?
Sexual fantasies, sexual dreams, sexual impulses, are all very normal phenomena, and there is no need to be ashamed of them at all. When people are maturing, as the body matures, the sexual organs mature, it is completely normal to start being curious about sex, and everyone is like that. It's just that we Chinese have not been civilized in sex education for a long time, so many young people will feel ashamed and hesitant about their sexual problems. >>>More
