If you can hear thunder are you close enough to get struck by lightng in a thunder storm?

If you can hear thunder, you are close enough to be struck by lightning. Thunder is the sound produced by lightning, so if you can hear it, you are within striking distance of a lightning bolt. It is important to seek shelter immediately in a safe location during a thunderstorm to reduce the risk of being struck by lightning.


Why there are cracks during thunder?

If thunder is close it makes a cracking noise, as opposed to a rumble. This is because lightning not only produces high electrical voltage, but as that voltage is released as lightning, a tremendous amount of heat is created. This heat is so great that it forces the are around the lightening bolt to expand, much like an explosion. If the lightening is close, you will hear a crack, but distance and air expansion dissipates that crack and turns it into a rumble. Generally speaking, the deeper the note of the thunder, the further away it is.

How thunders will be formed?

Thunder is formed when lightning rapidly heats the air around it, causing the air to expand very quickly and create a shock wave. This shock wave is what we hear as thunder. The sound of thunder can travel for several miles depending on atmospheric conditions.


Why do sometimes hear thunder at about the same time you see flash of lightning but other times you hear thunder after the flash?

If you hear the thunder almost at the same time as the lightning flash - the storm is directly overhead. Usually - the sound of thunder arrives a few seconds after the lightning, because light travels much faster than sound.


Why does thunder occur?

The rapid heating of the air from lightning creates a pressure wave in the air that we hear as a loud thunderclap. If its farther away we hear "rolling" thunder as the wave dissipates with distance; if it's close, the thunder can be a sharp crack !


Can you see thunder or lightning?

You see lighting and hear thunder.


What do thunder?

Thunder, as a pressurized sound wave, can hurt your ears, scare children and animals, and set off some car alarms. Since it is caused by the rapid heating of air produced by a nearby lightning strike, it can also alert you that it is no longer safe to be outdoors: if you're close enough to hear thunder, you're close enough to be at risk. +++ . You don't actually need the adjective "pressurised" because sound IS a train of pressure waves. . As for being "at risk" (from?) because you are close enough to hear the thunder, the time to worry is when you are below the thunder-cloud and there is little interval between lightning and thunder. The sound can carry for many miles, far beyond the danger area.


Do you see or hear lightning?

You see the lightening, and hear the thunder.
