Lightning is an electric current. To make this electric current, first you need a cloud. When the ground is hot, it heats the air above it. This warm air rises. As the air rises, water vapour cools and forms a cloud. When air continues to rise, the cloud gets bigger and bigger.
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions, both in the atmosphere or with one on the ground, temporarily neutralize themselves, causing the instantaneous release of an average of one gigajoule of energy.

What are lightning events used for?
Introduction Events in lightning are used to transfer a message or data between two different aura components. Events are useful when you want to send some data from one aura component to another to pass crucial information amongst components.

One inquiry we ran across in our research was “What is component event in Salesforce Lightning?”.
A component event is an event that is fired by a lightning component. A component event can either be handled by the component itself or it can be handled by any other component which is present in the hierarchy that receives the event.
The framework uses event-driven programming. You write handlers that responds to the interface events as they occur. In the Lightning Component Framework, events are fired by the Java. Script controller actions. Events can contain attributes that can be set before the event is fired and read when the event is handled.

What causes lightning to occur?
Lightning primarily occurs when warm air is mixed with colder air masses, resulting in atmospheric disturbances necessary for polarizing the atmosphere. However, it can also occur during dust storms, forest fires, tornadoes, volcanic eruptions, and even in the cold of winter, where the lightning is known as thundersnow.
The main bolt or stroke will go back up to the cloud. It will make a flash of lightning. It will also heat the air. The air will spread quickly. It will make the sound we hear as thunder. Lightning is dangerous. Here are some safety rules. Image above: Do not stand outside during a storm. Credit: NASA Stay away from open spaces.
How dangerous is lightning?
Lightning is a major cause of storm related deaths in the U. S. A lightning strike can result in a cardiac arrest (heart stopping) at the time of the injury, although some victims may appear to have a delayed death a few days later if they are resuscitated but have suffered irreversible brain damage. According to the NWS Storm Data, over the.
In essence, the person acts as a “short circuit” for some of energy in the lightning discharge. Side flashes generally occur when the victim is within a foot or two of the object that is struck. Most often, side flash victims have taken shelter under a tree to avoid rain or hail.
How does light work, and how do we see it?
