What is the difference between lightning and thunder? Thunder is merely the rumbling sound that lightning creates. You hear the thunder after you see the lighting because light travels faster than sound. Lightning is the light that is emitted, and thunder is the sound.

Lightning Distance Calculator The formula is to divide the number of seconds by the speed of sound in feet per second. The delay between when you see lightning and when you hear thunder occurs because sound travels much, much slower than light. Sound travels through air at about 1100 to 1200 feet per second (our default is 1150). That is a little more than one mile per five seconds.

- What causes thunder? Thunder is caused by lightning, which is essentially a stream of electrons flowing between or within clouds, or between a cloud and the ground. The air surrounding the electron stream is heated to as hot as 50,000 degrees Farhenheit, which is three times hotter than the surface of the sun.

The Science of Thunder The shock wave extends outward for the first 30 feet (10 m), after which it becomes an ordinary sound wave called thunder. The speed of sound through air at sea level is 758 mph (1,130 feet/second; 344 m/second) at 68° F (20° C). Thunder is exploding air occurring along the entire length of the lightning channel.

- The delay between when you see lightning and when you hear thunder occurs because sound travels much more slowly than light. Here's what you do: Let's say you counted 18 seconds. To find your distance from the lightning in miles, divide 18 by 5 to get 3.6 miles.

Thunderstorm A thunderstorm, also known as an electrical storm, lightning storm, or thundershower, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder. Thunderstorms occur in association with a type of cloud known as a cumulonimbus.

Thunder and lightning A thunderstorm is a series of sudden electrical discharges resulting from atmospheric conditions. These discharges result in sudden flashes of light and trembling sound waves, commonly known as thunder and lightning. Thunderstorms are associated with convective clouds and are often accompanied by precipitation.

How thunder sounds Light travels at 300,000 km/second, whereas sound travels at 0.3 km/sec. This is why you can see the flash of lightning sooner than you hear the rumble of thunder that the initial lightning strike produces. As the distance to the lightning strike increases, the pitch of the thunder lowers.

Lightning Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. Sheet lightning describes a distant bolt that lights up an entire cloud base. Other visible bolts may appear as bead, ribbon, or rocket lightning.

What causes thunder? Thunder is caused by lightning. Thunder is the sound caused by rapidly expanding gases a channel of lightning discharge. Lightning has enough energy to heat the air up to 18,000 degrees Fahrenheit. This causes a rapid spreading of the air, creating a sound wave heard as thunder. The sharp click or crack heard very near, right before the main crash of thunder.Thunder is the sound produced after a lightening strike.

- Light travels faster than sound so we see lightning before we hear thunder. The closer you are, the shorter the gap between the lightning and thunder. The speed of sound is around 767 miles per hour (1,230 kilometres per hour). The speed of light is around 669600000 miles per hour (1080000000 kilometres per hour).

Severe Weather 101 The flash of lightning temporarily equalizes the charged regions in the atmosphere until the opposite charges build up again. Lightning can occur between opposite charges within the thunderstorm cloud (intra-cloud lightning) or between opposite charges in the cloud and on the ground (cloud-to-ground lightning). Lightning is one of the oldest observed natural phenomena on earth. It can be seen in volcanic eruptions, extremely intense forest fires, surface nuclear detonations, heavy snowstorms, in large hurricanes, and obviously, thunderstorms.

What is Thunder? There is an old myth that counting seconds between a lightning flash and the accompanying thunder gives you the distance of how far away the storm is, in miles. However, from a mathematical point of view we know this isn’t true, as the speed of sound is roughly 330 metres per second.

Definitions &Translations The charged regions in the atmosphere temporarily equalize themselves through this discharge referred to as a strike if it hits an object on the ground. Although lightning is always accompanied by the sound of thunder, distant lightning may be seen but be too far away for the thunder to be heard.

- Thunder is the sharp or rumbling sound that accompanies lightning. It is caused by the intense heating and expansion of the air along the lightning channel. The rumble of thunder is caused by the noise arriving from parts of the channel at different distances. For this reason, thunder also lasts longer than the flash, and because sound speed is relatively low (see the next question).

Severe Weather 101 Lightning is a giant spark of electricity in the atmosphere between clouds, the air, or the ground. In the early stages of development, air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground. When the opposite charges builds up enough, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning.

- Since sound travels about 1 km every 3 seconds (or 1 mile every 5 seconds), and the extend of lightning is of the order of several km, thunder usually lasts several seconds. You hear different parts of the lightning channel(s) as the thunder continues. Thunder of IC lightning.

What Causes Thunder? These 10 animal facts will amaze you. Thunder is caused by the sudden expansion of the air around a lightning bolt's path. The deep rumbling and sharp cracks of thunder are produced as the air around the lightning bolt is superheated — up to about 54,000° Fahrenheit (about 33,000° Celsius) — and rapidly expands. This rapid expansion creates an acoustic shock wave that manifests itself as thunder. The closer the lightning is, the louder the clap of thunder will seem to be. Lightning is a discharge of electricity in the atmosphere.

Welcome to Weather Wiz KidsÂ®! Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges.

- Lightning can originate within a thunderstorm cloud and from the cloud to the ground. Intra-cloud lightning is basically a large spark of electricity that occurs between the positive and negative charges in the cloud with the air working as an insulator.

- A thunderstorm is a storm where you hear thunder and see lightning. Usually there is heavy rain in a thunderstorm. Thunderstorms are electric storms. When there is about to be a thunderstorm, a cumulonimbus cloud forms, often in a clear blue sky.

Understanding Lightning: Thunder Thunder is the sound caused by a nearby flash of lightning and can be heard for a distance of only about 10 miles from the lightning strike. The sound of thunder should serve as a warning to anyone outside that they are within striking distance of the storm and need to get to a safe place immediately!

What makes the sound of thunder? Does lightning make noise? Thunder can be heard up to 25 miles away from the lightning discharge. At these distances, thunder sounds like a low rumble because the higher frequency pitches are more easily absorbed by the surrounding environment, and the sound waves set off by the lightning discharge have different arrival times.

- Mani Gandham, adtech/enterprise/software/startups. Views. Thunder is the sound caused by lightning. When a lightning bolt strikes, the air immediately around it is superheated by the pressure and temperature of the electricity. This heated air rapidly expands and creates a sonic shock wave similar to a bomb explosion or when a jet breaks the sound barrier.
