In any country or anywhere we will encounter natural phenomena such as "Lightning". Lightning is also known as "Thindebolt". Lightning we often encounter when the rainy season comes. Lightning has a distinctive white spot and is followed by a loud noise. Lightning is a natural phenomenon that usually occurs anywhere when the rainy season arrives, not least in Indonesia. The so-called lightning is a blinding flash of white light, while the roar that comes after it is called thunder. Thunderbolts and band thunder together, but sometimes the time lag between lightning and thunder is short. This future time difference is due to the difference between the speed of sound and also the speed of light that occurs almost simultaneously.
Some people say that "Lightning" is a natural phenomenon, a natural phenomenon that really happens because there are some things that cause it to happen. Like the rain that occurs because there is evaporation on the planet Earth that rises above the sky, there is also lightning. Lightning occurs because of potential between cloud and earth or with other clouds. The occurrence of lightning also through several processes, as some experts say in the following summary.
- The process of occurrence of charge on this cloud because the clouds continue to move regularly and continuously. During this movement clouds will interact with other clouds so that the negative charge will gather on one side only and the opposite side will gather the positive side.
- Negative dumping occurs, it occurs when the potential difference between the cloud and the earth besar.Hal enough this will result in the disposal of negative charge from the cloud to the earth to achieve this kesetimbangan.Pada dumping process, the media through which electrons or air
- By the time the electrons are able to penetrate the threshold of the insulation of the air this is the explosion of sound we hear as a booming sound.
Thus we can conclude that the occurrence of lightning because during the rainy season air contains a higher water content so that the insulation power will go down and in accordance with the circulation.
