Thunder is always heard after lightning flashes. The sounds from thunder can be heard from miles away, but you can see lightning and NOT hear thunder. Never the other way around.

Why do you see thunder after you see the flash of lightning?

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.


Can you see thunder or lightning?

You see lighting and hear thunder.


Do you see or hear lightning?

You see the lightening, and hear the thunder.


How come you see lighting and do not hear it and how come you hear thunder and do not see it?

You see lightning before you hear it because light moves faster than sound. Thunder comes from the lightning. You can't hear it until the sound waves reach you.

Thunder and lightning occur roughly at the same time during a thunderstorm, but they are different things. Typically you see the lightning first and then you hear the thunder.

Can Lightning and thunder occur simultaneously?

No. Thunder is the result of lightning when it hits the ground. After lightning hits the ground the air expands (because of the increase in temp.) and quickly condenses. That air condensing is what we hear when there is thunder. Because light travels faster than sound we see lightning then hear thunder.


Why do thunder and lightning arrive at different times?

You will see the lightning before you hear the thunder because light travels faster than sound (:


Why is there a delay between the lightning an thunder?

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.


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.


When you see a lightning strike you will probably hear thunder soon is this a scientific theory or a scientific law?

Scientific law - the lightning 'spark' produces a sound wave when it discharges - which is what we hear as thunder.
