How does lighting and thunder accour , detailed explanation
Lightning is the most spectacular component of a thunderstorm. In fact, that's how thunderstorms got their names. Wait a minute, what does thunder and lightning have to do with it?
So lightning causes thunder. Thunder and lightning happen at the same time. They are each audible and visible products of the same phenomenon. However, since visible products (lightning) travel at the speed of light and thunder travels at the speed of sound (unless you get hit by lightning), you will feel the lightning before you feel the thunder. It's much faster than the speed of sound. Lightning is an electrical discharge.
- A single lightning strike can heat ambient air up to 30,000°C (54,000°F)! This extreme heat causes the air to expand rapidly. The expansion creates a shockwave that turns into a booming sound wave known as thunder.
- Because opposites are attracted, you want the negative charge at the base of a thundercloud to connect with the positive charge on Earth. As soon as the negative charge at the bottom of the cloud becomes large enough, a stream of negative charge called the step leader rushes towards the Earth. Since the positive charge on the ground is attracted to the step leader, the positive charge flows upward from the ground. When the step leader and the positive charge meet, the strong current carries the positive charge into the cloud. This current is called the reverse impulse. We see it as a bright flash of lightning.
- Another reason is why we see lightning first and then thunder. This is because the speed of light is faster than the sound of light, so we see lightning first and then thunder. If that lightning strikes you, thousands of amperes of current will flow through your body and your heart will stop beating. So stay home during lightning and thunderstorms, stay home and protect yourself and your family.
- If lightning strikes, unplug your TV, refrigerator, and unplug your mobile charger. This lightning strike can damage your device.
How does thunder sound after a lightning strike?
- Thunder is caused by the rapid expansion of the air surrounding the lightning's path. However, the grunts and growls you hear during thunderstorms are actually due to the rapid expansion of the air surrounding the lightning.
- The magnitude of thunder can be expressed in decibels (dB). Thunder is typically recorded at around 120 dB in the immediate vicinity of a ground strike. It's 10 times bigger than a garbage truck or pneumatic jackhammer.
Can lightning kill people?
- If you've ever thought about getting struck by lightning, you probably think it's going to come down from the sky and hit you, and that's it. you are dead.
- First, lightning hurts more people than it kills. In fact, approximately 90 percent of those lightning hits survive, but often with long-lasting neurological damage, says Dr. Mary Ann Cooper, a leading expert on lightning injuries.
- Second, lighting that hits someone directly from the sky is called a direct strike, “which hardly ever happens,” says Ron Holle, a meteorologist with Vaisala Global Atmospherics, Inc., in Tucson, Arizona, which operates the National Lightning Detection Network.
- You’ve probably heard that lighting which strikes a building can get into wiring or water pipes to kill someone talking on a phone with a cord or who is taking a shower. This happens, but such “contact strikes” are as rare as direct strikes. Direct and contact strikes each account for only 3-5 percent of lightning deaths and injuries. When a lightning strike of 20,000 amps or more strikes the ground, not all electricity simply dissipates into the ground. It travels along the ground as a potentially lethal current whose voltage decreases with distance from the point of impact.
- When lightning strikes a human animal, thousands of amperes of current flow through its body. This can lead to fatal accidents. And people can die.
