Why do we always see lightning before we hear thunder?

Because the speed of lightning is much faster than the speed of thunder, it is the lightning that is seen first and then the thunder is heard.

Why do we always send lightning and then wait to see that Thor is indeed like this, every time someone comes before, a lightning bolt comes over, followed by a lifetime of thinking? Sometimes it's really big. The speed of light travels faster than the speed of birth, so the light is seen first and then the sound is heard.

Here it is. Propagation at the speed of light. The full responsibility for the complaint is one of them.

The frame rate doesn't have the speed of light, so when the speed of light comes first, we see lightning first.

Lightning travels at the speed of light, and thunder travels at the speed of sound, with the speed of light being about 300,000 kilometers per second and the speed of sound being only 340 meters per second. So I saw the lightning first and slowly heard the thunder.

In the summer, thunder and lightning are common, and thunder is always heard a few seconds to a dozen seconds after the lightning has passed. Why is that? Lightning is an electrical spark produced when the charge generated by the cloud during its motion is discharged when it is discharged, and it is both light and sound.

In fact, lightning and thunder appear at the same time, and the reason why we see lightning first and then hear thunder is because in the air, light travels 3 million kilometers per second, while sound can only travel 1 kilometer in the air. The speed of sound is only one-900,000th the speed of light. Light travels fast and reaches the ground very quickly, while sound travels slowly in the air and travels to the earth after a while.

So you will hear the lightning first and then hear the thunder. Thunder is reflected when it hits clouds or tall buildings, so it usually takes a while for a while to disappear after a lightning bolt.

If it's a brain teaser, the eyes are in front of the ears. If it's a scientific problem, because light travels faster than sound, lightning and thunder are emitted at the same time, because of the speed of propagation, people always see lightning first, and then hear the sound of thunder

Because the speed of light is faster than the speed of sound, according to the resolution of the 15th International Conference on Weights and Measures in 1975, the speed of light in a vacuum was set at c 299 792 458 m seconds. In the usual application, take more than c = 3 10 8 m sec.

Electrons travel at a speed of 299,792,458 meters and seconds in a vacuum, which is about the size of the speed of light. However, the speed of electrons moving in a conductor is generally much lower than the speed of light because of the drag formed by matter. Because electrons have mass, the speed of movement of electrons in a vacuum can only be close to the speed of light, but not the speed of light.

About the speed of electricity: The speed of propagation of light is the speed of movement of photons, while the speed of propagation of electricity refers to the speed of propagation of the electric field (some people say that it is the speed of propagation of electrical signals, but it is actually the same), not the speed of movement of electrons. The electrons in the wire can move a few meters per second (macroscopic velocity) which is already a very high velocity.

Light travels faster than thunder.

I don't know why this is happening?

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.

It's a simple question. Because the speed of light is faster than the speed of sound, we see the flash point first and then hear the thunder.

It's too cold, so tired, Lou Mingmin, oh, oh, oh, oh.

Because the speed of light is much faster than the speed of sound, it appears, and lightning is seen first and then thunder is heard.

Because their propagation speed is very different, the speed of light is much greater than the speed of sound, which is why this happens.

Because sound and light travel at different speeds, light travels very fast, so we will see lightning first.

This is because light travels faster than sound. So you always see lightning first and then hear thunder.

In fact, thunder and lightning occur at the same time, but at different speeds, and the speed of light is faster than the speed of sound.

Because the speed of light travels much faster than the speed of sound. In the same medium, the light is seen first.

You know, because light travels much faster than sound in the same medium.

The reason why you hear thunder after watching lightning first is because in the air, light travels fast and reaches the ground very quickly, and the sound is there.

The speed of propagation in the air is slow, and it takes a while to reach the earth.

So you will see lightning first and then hear thunder. In fact, lightning and thunder appear at the same time.

The reason for so much difference in the time it takes to reach the ground is because the light travels every second.

3,000,000 kilometers, while sound in the air can only travel kilometers per second. The vocal cords have only light.

1 in 900,000 speed.

Some lightning bolts are long, some are short, some are loud, some are small. You can root.

The height of the clouds to the ground is roughly judged by the time it takes for the sound to reach the ground.

It barely takes much time for the light to reach the ground, and it can be considered zero, from the time you see lightning to the time you hear thunder.

How many seconds are multiplied by 340

Meters are the distance from lightning to you.

Thunder is reflected when it encounters clouds or tall buildings, so it usually takes a while for a lightning bolt to disappear.

Light travels much faster than sound travels through the air.

Brain teaser: Because the eyes are in front and the ears are behind.

Because the speed of light is higher than the speed of sound, lightning is seen first, and thunder is heard later.

Because the eyes grow in front and the ears in the back. (brain teaser).

Because light travels much faster than sound.

Because of the speed at which light transmits electricity, this thunder is fast.

Lightning and thunder are produced at the same time, but light travels much faster than sound.

So when thunder strikes, you see lightning first, and then you hear thunder.

In summer, thunderstorms often occur, and when it rains, lightning and thunder are earth-shattering. We know that when the electric field between the positive and negative charge regions in a thundercloud is large enough to a certain extent, the two charges will be neutralized and a spark will occur, and a strong light will occur when the spark is discharged, which is lightning.

When a high temperature is generated in the path of light, the surrounding air suddenly expands due to intense heating, and the cloud droplets will also suddenly vaporize and expand due to the high heat, causing a loud noise, which is called thunder.

Lightning and thunder occur at the same time, so why do we always see lightning first and then hear thunder? This is because light travels much faster than sound.

Sound is only 340 meters per second in the air, and light travels 300,000 kilometers per second in the air, which is 900,000 times the speed of sound! The time it takes for light to travel from the place where the lightning occurs to the ground is generally only a few hundred thousandths of a second, but it takes a long time for the sound to travel this distance. So, you will see lightning first, and then you will hear thunder.

Based on this common sense, we can use the time between the time we see the lightning and the time we hear the thunder to calculate how far away the discharged cloud is from us.

Sometimes we only see lightning and don't hear thunder, because the discharge clouds are too far away from us, or the thunder is not loud enough. As it spreads, its energy becomes smaller and smaller.
