Do we see lightning first or hear thunder first during thunderstorms, and why?

Lightning is seen first, then thunder is heard.

Lightning and thunder occur at the same time, and since in the air, the speed of light is faster than the speed of sound, so lightning is seen first, and thunder is heard later.

On a thunderstorm, lightning must be seen first and then thunder heard. Because in the air, lightning travels at the speed of light, 300,000 kilometers per second. Whereas, the speed of sound propagation is 360 meters per second.

We see lightning first and then hear thunder because light travels faster than sound!

In fact, lightning and thunder occur at the same time, but their speed of propagation in the atmosphere is very different, and the speed of light travels faster than the speed of sound, so we see lightning first and then hear thunder. Hope.

Generally speaking, lightning is seen first, and then thunder is heard. The main reason is that the speed of light is much faster than the speed of sound. When lightning strikes high in the sky, the light it emits reaches our eyes almost instantly. As for the sound, it is much slower.

The first thing you need to determine about this question is that both must appear at the same time. In the case of both at the same time, the lightning will definitely see the bright light faster than the sound. Because light travels faster in the air than sound.

Lightning is seen first, then thunder is heard. Because the speed of light travels faster than the speed of sound.

Hello, glad you asked, in a thunderstorm we all see lightning first and then hear thunder, because light travels much faster than sound.

Because the speed of light transmission will be a little faster. The speed of sound is a little slower, so we can see lightning and then hear thunder. That's the speed of the legend is not the same.

See lightning first because the speed of light is greater than the speed of sound.

Lightning and thunder occur at the same time, but we usually see lightning first and then hear thunder, which is true because light travels much faster in the air than sound. At 15, the propagation velocity of sound in the air is 340 m s, while the propagation velocity of light in a vacuum is 3 108 m s. The propagation speed of light in the air is slightly lower, and it is also approximated to be 3 108 m s, which is equivalent to the Earth's equatorial circle in 1 s.

It takes seconds for light to travel back and forth on the moon.

Sometimes the weather merges, the situation is aggravated, the clouds form strong convective weather, electrons are generated, light rays are formed, we call it lightning, lightning produces sound at the same time, because the speed of light waves in the air is faster than sound, the light is bright, we can see it at a glance, and then we hear thunder, normal weather, lightning when it rains, the speed of light is fast, we can't hear thunder; Without lightning, there is no sound. Lightning and thunder are caused by electrical discharges between clouds with a heterogeneous charge or between clouds and the earth.

When the clouds with a heterogeneous charge are at a distance, the positive charge causes the air to decompose and an instantaneous discharge is released. A spark is lightning, and a sound is thunder. Lightning and thunder occur at the same time, but in the air, the speed of light is fast and the speed of sound is slow.

The speed of light reaches the ground first, so the lightning is seen first. Light travels through the air at a speed of about 300,000 kilometers per second. At this speed, it travels seven and a half times around the Earth's equator in one second.

Sound travels through the air at a speed of about 340 meters per second, or about 900,000 times the speed of light.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Because the propagation speed of light is faster than the propagation speed of sound, light can be transmitted from the sky to the earth at a very fast speed in the process of propagation, but the propagation speed of sound in the air is 340 kilometers per second, so sound is a little slower than the speed of light.

This is because light travels faster than sound, so lightning is seen first, and thunder is heard after a while.

Because light travels faster in the air than sound, lightning is always seen before thunder is heard on a thunderstorm night.

Because the speed of light travels faster than the speed of sound, we see light and hear sound last.

Lightning and thunder occur at the same time, but the speed at which they travel through the atmosphere varies greatly, light can travel 300,000 kilometers per second, while sound can only travel 340 meters, so people always see lightning before they hear thunder.

According to this phenomenon, the distance from the place where the lightning occurred can be calculated from the length of the period of time from the time the lightning is seen to the time when the thunder is heard. If the lightning is in the northwest and thunder is heard every 10 seconds, it means that the thunderstorm is about 3,400 meters away.

In fact, the reason is very simple, because in the air light travels faster than sound, so you can see lightning first, and then you can hear thunder later, and you can calculate how far away the lightning is from you based on the speed of sound propagation.

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

Analysis: The speed of light is about 3 10 x 8 m s (3 10 to the eighth power), while the speed of sound is about 340 m s. At the same distance, it will definitely take less time for light to travel to the earth. So, in a thunderstorm, you see lightning first and then hear thunder.

Actually, lightning and thunder occur at the same time, except that lightning is light and runs very fast, while thunder is sound and runs much slower. Because the speed of light is 300,000 kilometers per second, it can circle the earth seven and a half times in one minute; And the speed of sound in the air is about kilometers per second.

The speed of light travels faster than the speed of sound.

Anyone who has studied physics knows that lightning and thunder are phenomena that people in nature can often hear and see. It usually occurs in clouds during severe convective weather. Because in the clouds, some clouds have a positive charge, some clouds have a negative charge, due to the characteristics of charge repulsion of the same sex, opposites attract, and also because of the positive and negative charges carry the accumulated energy is huge, the current is very large, the voltage is very high, when the positive and negative charges are close, it will break through the air and produce a huge ** sound, forming light and heat, which is the discharge process of lightning, and it is also the reason why people see lightning and hear thunder.

In fact, flash and thunder occur almost at the same time, so why do people always see lightning first and then hear thunder? The main thing is that light travels much faster in the air than sound travels through the air. (Light travels at a speed of 299792458 meters in the air, or about 300,000 kilometers per second, while sound travels at a speed of only 346 meters in the air.)

It is the reason why the speed of light is much greater than the speed of sound.

Lightning is accompanied by thunder, but we all see lightning in the clouds in the distance before we hear thunder, because the speed of light is much greater than the speed of sound.

The speed of light is 300,000 kilometers per second, while the speed of sound in the air is only 340 meters and seconds. And thunder, although it also occurs at the same time as lightning, the sound runs slowly, and it takes a while for it to reach our ears. So we tend to see lightning first and hear thunder after a while.
