Thunder and lightning are the same thing, aren t they?

It's not the same, the speed of lightning is 3 times 10 to the 8th power of meters per second, thunder is the speed of sound is only more than 300 meters per second, generally there is lightning first, and then thunder! Ha ha.

The sky was cloudy, and when the thunderstorm clouds were rapidly developing, suddenly a dazzling flash of light pierced the sky, followed by a deafening loud sound, which was lightning and thunder, also known as thunder and lightning. Thunder is an atmospheric acoustic phenomenon, which is a sound wave formed by a shock wave generated strongly in a small area of the atmosphere, while lightning is a spark discharge phenomenon that occurs in the atmosphere.

Lightning and thunder occur at the same time, but the speed at which they travel through the atmosphere varies greatly, so people always see lightning before they hear thunder. Light can travel 30 kilometers per second, while sound can only travel 340 meters. According to this phenomenon, we can calculate the distance from us from the time we see the lightning to the time when we hear the thunder.

If lightning is in the northwest and thunder is heard every 10 seconds, it means that the thunderstorm is about 3,400 meters away.

Lightning usually occurs when there are thunderclouds, but occasionally during thunderstorms, Nimbostratus, dust storms, and volcanic eruptions. The most common form of lightning is line lightning, but occasionally banded, spherical, string-shaped, branch-like, arrow-like lightning and many more can occur. Linear lightning can be generated within clouds, between clouds, and between clouds and the ground, of which lightning in and between clouds accounts for most of the lightning, and lightning between clouds and the ground accounts for only one-sixth, but it is the most harmful to humans.

Thunder and lightning are the same thing – the phenomenon of electrical discharge. Two clouds in the sky, one with a positive charge and the other with a negative charge, when they charge enough and are relatively close, there will be a discharge between them, and the light emitted when discharging is lightning, and the ** sound emitted at the same time is thunder. Since light travels much faster in the air than sound, we always see lightning first and then hear thunder.

The phenomenon of discharge occurs not only between clouds but also between clouds and ground.

No. Thunder is the sound of lightning formed by the discharge of clouds, and lightning is the electric arc generated by the electric potential of charged clouds that is high to a certain extent, ionizing the air and turning the air into a conductor.

The reason why there is lightning and then thunder is because in the air, light travels faster than sound. In fact, lightning and lightning occur at the same time, but the speed of light is 300,000 kilometers per second, while the speed of sound is only about 340 meters per second. It can be seen that sound travels slower than the speed of light.

So when thunder strikes, you will see lightning first, and then you will hear thunder. Sometimes the thunder drags on for a long time, which is caused by clouds, mountain peaks and the ground reflecting the thunder back and forth.

When it rains, some of the clouds in the sky are positive and some are negative. When two clouds collide, lightning strikes, and at the same time emits a lot of heat, heating and expanding the surrounding air. The air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration.

This is thunder.

The formation of thunderstorm clouds generally requires two conditions, sufficient water vapor and violent convective movements. In winter, due to the cold and dry air and weak solar radiation, convection is not easy to form in the air, so thunder and lightning are rare. However, sometimes thunderclouds are formed in winter when the temperature is high, and thunder and lightning are generated, and rain and snow occur.

During thunderstorms, thunderstorms and lightning, do not dial and answer, and unplug the wire. Mobile phones can be used normally, but generally try not to receive mobile phones outdoors or indoors near windows. During thunderstorms and lightning, do not turn on TVs, computers, VCDs, etc., and unplug all power plugs to avoid injury and damage to electrical appliances.

When the thunderstorm is heavy, stay away from the trees, try not to run in stride, and choose buildings to take shelter from the rain.

Summary. There are three differences between thunder and lightning: First, the principle of the two is different

1. The principle of thunder: when it rains, some of the clouds in the sky are positive and some are negative. When the two clouds collide together, lightning will be emitted, and at the same time, a lot of heat will be released, so that the surrounding air will be heated and expanded, and the air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration, which is thunder.

2. The principle of lightning: lightning is a strong discharge phenomenon between clouds and clouds, between clouds and the ground, or between various parts of the cloud body (generally occurs in cumulonimbus clouds). <

There are three differences between lightning and lightning: 1. The principle of the two is different: 1. The principle of thunder:

When it rains, some of the clouds in the sky are positive, and some are negative. When the two clouds collide together, lightning will be emitted, and at the same time, a lot of heat will be released, so that the surrounding air will be heated and expanded, and the air that is heated and expanded in an instant will push the surrounding air, causing a strong **-type vibration, which is thunder. 2. The principle of lightning:

Destroying lightning is a strong electrical discharge between clouds, between clouds and the ground, or between parts of the cloud body dust imitation (generally occurs in cumulonimbus clouds). <

2. The reasons for the formation of the two are different: 1. The reason for the formation of thunder: the thunderstorm Wang Xiaoxun is due to the strong convection of warm and moist air in local places, and the sharp rise of warm air produces the violent vibration of cumulonimbus clouds, which will accumulate a large amount of charge and produce thunder.

2. The reason for the formation of lightning: the discharge of charged clouds to the earth is generally the case, and the clouds belong to the high potential of the positive charge region, and the earth is at the low potential of the negative charge region. Air is originally non-conductive, but under the action of a strong electric field force, the outermost electrons of the gas nucleus will be excited by the electric field force to produce a transition and form charged ions.

The atom that gains electrons is called a negative ion, and the atom that loses an electron is called a positive ion. Under the action of the electric field force, charged ions can form a flow of electrons. Third, the essence of the two is different:

1. The essence of this thunderstorm: the propagation of sound. 2. The essence of lightning:

Propagation of light. <>

There is no difference between thunder and lightning, both refer to the phenomenon of electrical discharge in the sky. In English, it is used to refer to thunder.

The so-called lightning in life refers to seeing lightning without making sound, and thunder is seeing lightning and hearing sound, which is caused by the fact that light travels faster than sound. However, both lightning and thunder occur by colleagues, but the speed of propagation is different, so there is a saying that lightning strikes first and then thunder.

Turning off household appliances is often due to the fact that when the electrical appliances are exposed to lightning on a lightning day, it is easy to cause lightning drainage, which may lead to dangerous phenomena.

Therefore, on thunderous and rainy days, it is important to avoid contact with electrical appliances or other non-insulators.

Lightning is a large-scale electrical discharge phenomenon that occurs in the sky. Clouds in the sky are electrically charged, some positively charged and some negatively charged, and large-scale discharges occur when two clouds with different kinds of electricity are close to each other. The electric spark that appears when discharging is lightning, and the sound it makes is thunder.

Electric sparks and thunder are generated at the same time, and because the cloud where the discharge occurs is far away from us, the light travels relatively fast (about 300,000 kilometers per second) and the sound travels relatively slowly (about 340 meters per second), so it is often the lightning that is seen first and then the thunder. Thunder and lightning are natural phenomena that occur when clouds in the sky carry a large amount of positive and negative electricity, and the positive and negative electric clouds meet.

Cause of thunder: It is now known that a large amount of light and heat is emitted when the charge is neutralized, and a large amount of heat is released in an instant, which will heat the surrounding air to a high temperature of 30,000. When a strong electric current passes through the air, it causes the air along the way to expand suddenly, and at the same time pushes the surrounding air, causing the air to vibrate violently, and the sound produced at this time is thunder.

Lightning is a pulsed discharge in the atmosphere. A lightning bolt consists of multiple discharge pulses, all of which have short intermittent times of only a few hundredths of a second. One pulse after the other, the subsequent pulses follow the channel of the first pulse.

It has now been studied that each discharge pulse consists of a "pilot" and a "backlash". The first discharge pulse is preceded by a preparatory phase – a "step-pilot" discharge process: the free charge in the cloud is quickly moved to the ground by a strong electric field.

If we add a very high voltage between the two electrodes and bring them closer together. When two electrodes are brought close to each other, an electric spark occurs between them, which is known as "arc discharge".

Lightning occurrence conditions.

1 The air should be very humid.

2 The clouds must be very large, dark; Generally Cumulonimbus clouds3 Areas with dry weather are generally less prone to thunder and lightning.

Causes of the formation of lightning.

In thunderstorm clouds, air currents generate static electricity due to the friction and decomposition of water molecules. There are two types of electricity. One is the positive charge with the positively charged particles, and the other is the negative charge with the negatively charged particles.

Positive and negative charges attract each other, like magnets. The positive charge is at the upper end of the cloud, and the negative charge attracts the positive charge on the ground at the lower end of the cloud. The air between the clouds and the ground is both an insulator that prevents the current of the charge at the poles from passing through.

When the charge in the thundercloud and the charge on the ground become strong enough, the two parts of the charge will break through the air barrier and come into contact to form a strong current, and the positive charge and the negative charge will come into contact. When these opposite-sex charges meet, a neutralizing effect (discharge) occursThe intense neutralization of the charge emits a large amount of light and heat, and these emitted light forms [lightning].

Most lightning bolts are connected twice. The first time it is called a pilot flash, it is an invisible air called a leader, and it goes down to the place close to the ground. This stream of live air acts like a wire, creating a path for the second current.

The moment the lead approaches the ground, a reconnect current jumps up along the path, and the flash produced by the reconnect is what we normally see as lightning.

The cause of thunder.

It is now known that when the charge is neutralized, a large amount of light and heat is emitted, and a large amount of heat is released in an instant, which heats the surrounding air to a high temperature of 30,000 degrees Celsius. When a strong electric current passes through the air, it causes the air along the way to expand suddenly, and at the same time pushes the surrounding air, causing the air to vibrate violently, and the sound produced at this time is thunder. (Don't forget to tell your little one that thunder and lightning happen at the same time, because the speed of light is much faster than the speed of sound, so we always see lightning before we hear it.)

If lightning strikes closely, we hear a deafening rumble. If lightning falls far away, we hear the rumbling of thunder. This is because of the echoes emitted by sound waves when they are refracted by the atmosphere and reflected by objects on the ground.

Lightning and lightning are two names for the same phenomenon. For example: a house has been struck by lightning; A certain house was struck by lightning, the same meaning.

The principle of the phenomenon process is: water droplets in the clouds collide and rub against each other, creating an electric charge. When the cloud charge reaches enough, they discharge each other or to the ground. This discharge phenomenon is called lightning or lightning.

Lightning and thunder are the same thing, occurring at the same time, except that light travels very fast at about 300,000 kilometers per second, and sound travels at a slower rate (in the atmosphere) by about 300 meters per second. So we see lightning first and then hear thunder.

When you hear the sound of lightning (speed of light, 3'5 to the 8th power of 10), saw thunder (speed of sound, 340 meters per second)! Explain that you have a special function!

Lightning is the propagation of light, and thunder is the propagation of sound. There is a clear difference between the two. Thunder is often accompanied by lightning, which occurs at the same time, but the order of perception varies depending on the ability to spread

Lightning and thunder are a kind of imagination of nature.

The two clouds have different charges, and when they collide together, they emit electric sparks, which is the lightning they see, and they make a sound that is the thunder they hear.

It's like hitting another with an iron bar, and you can hear the sound of duangduang and see the sparks!

Thunder is the part that has a strong flash of light, and can emit thunder and has a shock wave. Lightning is the part of the thunder that has a strong flash and can emit thunder, but it only has an electrical discharge effect on the earth or other objects, and the part that can only see the lightning light through the air without sound. Because electricity, no matter how strong it is, passes through the air without sound.

That is to say, if you are in an open area, the thunder is relatively high in the air, and after seeing a powerful flash, the lightning does not hit you, and the electricity may hit you, because the thunder and lightning travel through the air slightly slower than the speed of light.

Thunder is the result of lightning collisions.

Electricity is the cause of thunder.

In storm clouds, the air currents cause small water droplets to collide with each other until they are filled with electrical charges. Lightning is a huge spark of electricity generated by the release of an electric charge, and the lightning heats the surrounding air in such a short time, making a loud, rapid sound thunder.

Thunder is the sound that is made when clouds are discharged. Thunder and lightning are two completely different natural phenomena, one refers to sound, which is listening; One refers to the image, is to see. Most of the time they occur at the same time.
