Why is thunder slower than lightning? Which is faster and why, thunder or lightning

In fact, thunder and lightning occur at the same time, and since light travels faster in the air than sound travels in the air, we will see lightning first and then hear thunder.

Why do you hear thunder after seeing lightning first Article source: Date:2005-07-23 In summer, thunder and lightning often occur, and thunder is heard only a few seconds to more than ten seconds after the lightning.

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. It's just that the light and sound in thunder and lightning are more powerful than the electric sparks we see in our lives. The reason why lightning is seen first and then thunder is heard is because in the air, light travels fast and reaches the ground quickly, while sound travels slowly in the air and reaches the earth after a while.

So you will hear the lightning first and then hear the thunder. In fact, lightning and thunder appear at the same time. The reason for such a difference in the time it takes to reach the ground is that light travels 3,000,000 kilometers per second, while sound travels only one kilometer in the air.

The speed of sound is only one-900,000th the speed of light. Some lightning bolts are long, some are short, some are loud, and some are quiet. You can roughly judge the height of the clouds to the ground based on the time it takes for the sound to reach the ground.

It doesn't take much time for the light to reach the ground, it can be considered 0, from seeing lightning to hearing thunder, how many seconds is the interval and multiplied by 340 meters, which is 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.

Due to the very fast speed of light (3000000000 m s), you can basically see just lightning, even if lightning is on the moon you can see it in 1 second (if there is lightning on the moon and you can see it =. = So the question can be approximated as how many seconds it takes for you to hear the thunder travel to your ears. The speed of sound in the air is about 340m s, so if the place of thunder is 1km away from you, then lightning is about 3 seconds faster than thunder.

Lightning is faster. Thunder is sound, lightning is light. The speed of light is greater than the speed of sound, which is 882353 times the speed of sound, so lightning is significantly faster than thunder.

Thunder is a phenomenon that accompanies lightning. As it sounds, thunder can be divided into three types. One is the crisp sound of hunger and trie, like the thunder of **, which is generally called "explosive thunder"; The other is a dull rumbling sound, which some people call "muffled thunder".

There was also a low, long-lasting rumble, somewhat like the sound of grinding. Lightning is an intense electrical discharge between clouds, between clouds and the ground, or between parts of the body of the clouder.

Lightning is faster than thunder, as follows:

Lightning travels at the speed of light, 300,000 kilometers per second.

Thunder is moving at the speed of sound, 340 meters per second.

So it is lightning fast because lightning travels at the speed of light and thunder travels at the speed of sound, and the speed of light is 882353 times the speed of sound.

In the summer, when it is cloudy, lightning is often seen and thunder is heard. Why is there lightning and thunder? The sun shines on the earth, causing the water to evaporate into water vapor.

The air rises to the sky with water vapor. The air rises very quickly, and the water vapor accumulates more and more into clouds, at which point the water vapor becomes small water droplets. Each small droplet carries a little bit of electricity, that is, every small droplet has a small charge.

Billions of small droplets gather in a cloud, and billions of electric charges are carried in a cloud. The whole cloud carries electricity, and when the charge is very large, the electricity jumps from the top of the cloud to the bottom of the cloud. The lightning phenomenon happened.

That's when we see a dazzling bolt of lightning. As the lightning passes, thunder is heard. Why is there thunder?

When there is a flash, the air is heated and the temperature increases. Around the lightning, the hot air is pushed out. The air is pushed out faster than the speed of sound, and the air makes a sound, and then you hear a loud sound, which is thunder.

The thunder we hear is sometimes a boom, sometimes like a ** sound. Thunder is lightning pushing the air, and the air makes a roaring sound.

Everybody knows that.

These are two natural phenomena on rainy days.

Especially in the summer.

Thunder rumbled.

Lightning pierces the sky.

It's thrilling.

The faint-hearted are too scared to go out.

Especially cats and dogs are frightened to the point of being embarrassed.

Some people say that God punishes the bad guys.

There were five thunderstorms in the sky.

Scientifically speaking.

Thunder and lightning.

They are all physical phenomena in nature.

Thunder is the collision of positive and negative poles and clouds.

and emitted a fierce loud noise.

Lightning is clouds with clouds or inside clouds.

or the phenomenon of electrical discharge between clouds and heaven and earth.

In general.

See the lightning first.

Only then did thunder be heard.

Because light runs faster than sound.

The speed of light is 30000000m s

Sonic speed 3400m s

Anyway.

Sound and light though have no wings.

But free to gallop between heaven and earth.

No one can stop it.

The thunder was deafening.

But it is not very harmful to people.

Lightning is an extremely high-voltage power source.

Electric tigers are amazing.

It is very harmful to human beings.

We often say that someone was killed by lightning.

More scientific statements.

Not killed by thunder.

Instead, he was electrocuted.

Lightning harms. So.

On a thunderstorm day. Take precautions.

Do not take shelter from the rain under the eaves of a tree.

Don't wear metal hats.

Don't run around in the rain.

Once touched by an electric tiger.

It's hard to save a small life.
