In simple terms... light travels much faster than sound. We see the lightning flash first, followed by the sound when it finally reaches us
The flash of light travels much faster to our eyes, than the sound of the thunder to our ears.
Light travels faster than sound.
A typical lightning strike lasts for about 0.2 to 0.3 seconds.
If the center of the storm is directly over you, the thunder and lightning occur simultaneously - and startlingly loudly. But most of the time, we see the lightning well before we hear the thunder because you see things instantaneously, due to the speed of light. But you hear things much more slowly. It takes five seconds for sound to travel a mile. Hence, if you see lightning, then hear the thunder ten seconds later, the center of the storm is two miles away.
Since light travels faster than sound, you can tell how many miles away a thunder storm is by counting. Lightning strikes. 5 seconds pass and you heard thunder. The thunder storm is 5 miles away.
You see lighting and hear thunder.
Light travels faster than sound.
You don't see thunder. You hear thunder. You hear thunder after seeing the lightning because light travels faster than sound. The further the storm away is, the bigger the time between when you see the lightning and hear the thunder.
then the lightning is 2.78 miles away from you.
There is a delay between seeing the lightning and hearing the thunder because the speed of light (lightning) is much faster than the speed of sound (thunder). Thus, you SEE lightning first, and then you HEAR thunder later.
5 miles away
A typical lightning strike lasts for about 0.2 to 0.3 seconds.
If you mean hearing thunder right after a lightning, it is because sound travels slower than light, and thus, you would hear the thunder a bit later than seeing a lightning strike.
There are two:Herd - a group of animals, like a herd of cattle.Heard - past tense of hear. He heard the thunder 5 seconds after seeing the lightning.
the lightning is roughly a mile away
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.
lightning heats the air which we hear as thunder
