Why do you see lightning first and then hear thunder when it strikes?

In the summer, we often encounter thunderstorms, do you ever pay attention to always see lightning first, then hear thunder, you may think that lightning first and then thunder; It may also be thought that the place of thunder is far away from us, and the place of lightning is close to us. Actually, this is not the case, let's first take a look at how lightning is generated. Lightning and thunder are a phenomenon in nature.

The clouds in the sky are charged due to the irradiation of sunlight and friction and induction, and when the clouds with two different charges approach, the phenomenon of discharge will occur, and it will also emit flashes and ** sounds, which is the thunder and lightning in the air. It can be seen that lightning and thunder occur at the same time and in the same place, the flash of lightning is transmitted in the air at a speed of 300 million meters per second, the speed of lightning is only 340 meters in the air, and the speed of light in the air is about 882353 times the speed of sound, and the light is much faster than the propagation of sound. According to SV, although lightning and thunder occur at the same time, we always see lightning and then hear thunder.

Physics knowledge in junior high school: The speed of light is 3 10 per second to the eighth power. The speed of the sound is 340 meters per second.

When thunder strikes, thunder and lightning occur at the same time, so why do we see lightning first and then hear thunder? This is because the speed of lightning is 300,000 kilometers per second, and the speed of thunder is 340 meters per second, so when thunder strikes, lightning can be seen instantaneously, and thunder takes a while to hear.

Because light travels faster than sound, lightning is seen first, and thunder is heard later.

<> when thunder strikes, you see lightning first and then hear thunder, because the speed of light transmission in the density of the earth's atmosphere is about 294,000 kilometers per second, and the propagation speed of sound is about 342 meters and seconds.

In our lives, many natural phenomena are relatively common, especially in rainy days, we can often see the phenomenon of thunder, but when thunder is generally seen first and then thunder is heard, there is a certain reason, so let's introduce it to you.

First of all, as long as we have studied physics in junior high school, we can know that the speed of light is much greater than the speed of sound, which is the phenomenon that we can always see things and hear sound first, and this is also a normal phenomenon. Many people think that this symptom occurs because there is a certain problem in our body, but it is not the case, this is a normal phenomenon, don't worry too much, we must know that thunder and lightning occur at the same time, but because the speed of light is much faster than the speed of sound, we often see lightning first, and then hear thunder. In addition, we can often see some other phenomena in life, all of which are seen first and then heard, because there are many natural phenomena, and at the same time, they cannot be explained by some scientific evidence, as long as we know that this is a correct phenomenon.

You must know that once the thunderstorm occurs, the impact on our body is still very large, so try not to go out when the thunder occurs, and it is best to stay at home.

It can be seen that when it rains, in addition to the occurrence of thunder, there may also lead to lightning, you must know that the direction of lightning is uncontrollable, so you must pay attention to the way to avoid rain in life, in addition to thunder and lightning once it happens, then it also means that it is a rainy season, at this time we must not be under the tree, nor in a place close to the wire, otherwise it is likely to cause lightning to strike us, thus causing a certain impact on our body.

Finally, I would like to advise some young friends that it is best to check the weather forecast every day, so that they can decide whether to bring an umbrella or wear thick clothes according to the weather on the second day.

This is because the speed of light travels faster than sound, so people see lightning before they hear thunder.

Because the speed of light is much greater than the speed of sound, it is always the first time you see lightning and then hear thunder.

This is due to conduction, which allows light to travel faster than sound.
