Lightning comes first or thunder comes first, thunder or lightning strikes first?

Lightning, is the phenomenon of electrical discharge between two charged clouds in the air. When discharging at the same time, there is a loud noise, which is thunder. Lightning and thunder have the same origin.

But the speed of light is 300,000 kilometers per second, and the speed of sound is about 340 meters per second. Lightning always sees first, and then thunder comes slowly.

In lightning, lightning and thunder are produced at the same time, but people always see lightning before they hear thunder, and that's because.

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

Thunder travels at a speed of about 340 meters per second.

It can be seen that the speed of lightning is much faster than that of thunder.

And they travel the same distance to you.

So it takes less time for lightning to reach you than thunder.

So there will be a situation where you see lightning first and then hear thunder

1. Thunder and lightning actually occur at the same time, but the speed of light is faster than the speed of sound, so we see lightning first and then hear thunder.

2. Thunder and lightning are due to a discharge phenomenon between clouds with different charges or between clouds and the earth, when the distance between clouds with different charges is reduced to a certain distance due to movement, the strong electric potential difference between the negative charges will break through the air and instantaneously discharge, the discharge spark generated during discharge is the lightning we see, and the sound produced during discharge is thunder.

During a thunderstorm, lightning comes first because the speed of light is faster than the speed of sound.

Thunder and lightning occur at the same time, and we see lightning first and then hear thunder becauseIt is because light travels faster in the air than sound.

Thunder and lightning is a majestic and somewhat intimidating electrical discharge phenomenon accompanied by lightning and thunder. Thunder and lightning are generally generated in cumulonimbus clouds with strong convection, so they are often accompanied by strong gusts of wind and heavy rain, and 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 distribution of charges in the cloud is more complex, but in general, the upper part of the cloud is dominated by positive charges and the lower part is dominated by negative charges. As a result, a potential difference is formed between the upper and lower parts of the cloud. When the potential difference reaches a certain level, an electric discharge will be generated, which is our common lightning phenomenon.

The average current of lightning is 30,000 amps, and the maximum current can reach 300,000 amps. The voltage of lightning is high, about 100 million to 1 billion volts. A moderate thunderstorm can reach 10 million watts, which is equivalent to the output of a small nuclear power plant.

During the discharge, due to the sudden increase in temperature in the lightning channel, the volume of air expands dramatically, resulting in a shock wave that causes a strong thunderclap. When a charged thundercloud comes close to a protrusion on the ground, a violent discharge occurs between them. At the site of the lightning discharge, there will be a strong flash of light and a roar.

This is the lightning and thunder that people see and hear.

Summary. Lightning followed by thunder.

Lightning followed by thunder.

Lightning followed by thunder is a common natural phenomenon, especially during thunderstorms. This phenomenon occurs because lightning and thunder travel at different speeds.

Lightning is a phenomenon of electric discharge, which travels very fast and can reach more than 300,000 meters per second. Thunder, on the other hand, is the sound produced by lightning in the air**, and it travels relatively slowly, only about 340 meters per second. When lightning occurs, it spreads instantaneously to our eyes in the form of light, whereas thunder needs to travel some distance in the air before it can be heard.

As a result, we usually see lightning first and then hear thunder. In addition, lightning and thunder also have different travel paths. Flashing lightning is usually a discharge between clouds or between a rocky cloud and the ground, and its path is relatively direct; Thunder, on the other hand, needs to be refracted repeatedly in the air before it reaches our ears.

Question 1: Lightning or thunder first In fact, it happens at the same time, but because light travels faster than sound, we all see lightning first and then hear thunder.

Question 2: Thunder or lightning first, why from a person's point of view: see lightning first and then hear thunder. Because the speed of light is greater than the speed of sound ... In fact, thunder and lightning occur at the same instant.

Question 3: Thunder or lightning first Thunder first, thunder will have lightning. Some people have to ask why there is a sound of thunder after seeing internal electricity first, because the speed of light is faster than the speed of sound.

Question 4: Lightning or Thunder Actually happens at the same time, but because light travels faster than sound, we all see lightning first and then hear thunder.

Question 5: Thunder or lightning first, why from a person's point of view: see lightning first and then hear thunder. Because the speed of light is greater than the speed of sound ... In fact, thunder and lightning occur at the same instant.

Question 6: Thunder or lightning first Thunder first, thunder will have lightning. Some people ask why there is a sound of thunder after seeing internal electricity first, this is because the speed of light is faster than the speed of sound.

Summary. Thunder and lightning occur at the same time.

Thunder and lightning occur at the same time.

Due to a discharge phenomenon between clouds with heterogeneous charges or between clouds and the earth, when the distance between clouds with heterogeneous charges is reduced to a certain distance due to movement, the strong potential difference between positive and negative charges breaks down the air and instantaneously discharges, and the discharge spark generated during discharge is the lightning macro we see, and the sound produced during discharge is thunder. In the same way, when the charged cloud is moving, the corresponding place on the ground generates an induced charge, and if the distance between the cloud and the ground or a tall object on the ground is small, the air between the cloud and the object is broken down and an instantaneous discharge occurs to produce thunder. We see lightning first and then hear thunder, because the speed of light travels much faster than the speed of sound, so Liquid Minfan sees lightning first and then hears thunder.

Summary. Glad to answer for you: thunder or lightning first? Thunder first. Because light travels faster in the air than sound.

Glad to answer for you: thunder or lightning first? Thunder first. Because light travels faster in the air than sound.

Thunder followed by lightning, because thunder is the sound produced by lightning. When lightning strikes the ground, it produces a ** sound, which is thunder.

Thunder and lightning actually happen at the same time, but the speed of light is faster than the speed of sound, which is why we see lightning first and then hear thunder. Thunder and lightning are due to a phenomenon of discharging between clouds with different charges or between clouds and the earth, when the distance between clouds with different charges is reduced to a certain distance due to movement, the strong potential difference between the negative charges breaks down the air and instantaneously discharges, the discharge spark generated during discharge is the lightning we see, and the sound produced when discharging He Fiber is thunder.

1. Thunder and lightning actually occur at the same time, but the speed of light is faster than the speed of sound, so it causes us to see lightning first, and then hear thunder in the extremities. 2. Thunder and lightning are due to a discharge phenomenon between the clouds with different charges or between the clouds and the earth, when the distance between the clouds with different charges is reduced to a certain distance due to movement, the strong potential difference between the negative charges will break down the air and cause instantaneous discharge, the discharge spark generated during discharge is the lightning we see, and the sound produced during discharge is thunder.
