Thunder and lightning occur at the same time

[zakiyatasnim]

A lightning rod in a house is a metal element placed on the roof, which is connected to the ground and is reliably insulated from the structure of the house. Due to the fact that lightning takes the shortest path to the ground, it enters this element and is safely discharged without causing damage to other objects. For example, the famous Empire State Building is struck by lightning about 25 times a year.



Usually, it doesn't make sense to put lightning rods on every luxembourg number data house - one is enough for a relatively large area. Of course, it should be on the tallest building or a special tower.

Why is thunder heard after lightning?
Probably many people know the answer to this question, but without it the story would not be complete. Here it is enough to delve into physics and the answer will appear by itself.

Thunder is the result of the release of a large amount of energy when lightning strikes. It should be understood that thunder is sound, and lightning is light. The speed of sound waves at the Earth's surface is approximately 340 meters per second. The speed of light is 300,000 km per second.

For a rough calculation, we can assume that light reaches us instantly without delay, and sound travels 340 meters in one second. As a result, by multiplying the number of seconds between the flash and the time we hear thunder by 340, we can get the distance to the lightning in meters.

Lightning and planets
Lightning can appear not only on our planet, but also on others, if there are favorable conditions for their formation - a gaseous environment. For example, lightning can be observed on Saturn, Uranus, Venus and Jupiter. On some of these planets, lightning is hundreds, thousands and even millions of times more powerful than on Earth.
