When lightening strikes both the light and the sound are created at the same time and they start traveling towards you, wherever you are away from it. But, since the light travels faster than the sound you first see the lightening and then after a short pause you hear the thunder. The further you are away from the lightening strike the more time there is between when you see the lightening and when you hear the sound. That is because the speed of light is about one million times faster than the speed of sound.
Sound velocity in dry air is 33.45 m/sec. Light speed is 2.99792458 x 10 to the power of 8 m/sec. So, you can see that light is much faster than sound.
What else can I help you with?
Is it true that thunder is the sound lighting?
Yes. Thunder is the sound of lighting hitting the ground. Light travels much faster than sound so you see the lighting first and hear the thunder afterwards. If you see the lighting and hear the thunder right after, then you are closer to wear the lighting struck.
Would you hear thunder or see lighting first?
Even though the lightning and thunder occur at roughly the same time, you would see a distant strike before you would hear it, because the light travels to you about 882 thousand times as fast as the sound does.
Why doesn't thunder and lighting happen at the same time?
Actually, thunder and lightning DO happen at the same time, but unless you are within the immediate proximity of the lightning strike, the observer usually sees the flash before hearing the thunder because light travels much faster (~11,000,000 mph) than sound (~750 mph).
When did thunder start?
Celtic Thunder had their first performance in August of 2007
Is it really true that the lightning strikes first before the thunder or the lightning and thunder strikes together but only the lightning seems to be first because of it's speed of light?
Lightning does indeed strike first, as thunder is the sound created by lightning. According to Wikipedia, lightning heats the air surrounding it by large quantities, which in turn causes the air to expand and create a "Sonic wave" which is similar to a sonic boom.
Is it true that thunder is the sound lighting?
Yes. Thunder is the sound of lighting hitting the ground. Light travels much faster than sound so you see the lighting first and hear the thunder afterwards. If you see the lighting and hear the thunder right after, then you are closer to wear the lighting struck.

Does thunder always mean lightning?
No, thunder doesn't always mean lightning. Thunder is the sound produced by the rapid expansion of air around a lightning bolt as it heats up creating a shock wave. So while thunder is commonly associated with lightning, it is possible to have thunder without seeing the accompanying lightning, especially if the lightning is far away or obstructed from view.

How many days in advance of the first lighting of the candle is it appropriate to put out the menorah?
There's no rule. It's just a matter of preference. But usually, it is set up the day before the first evening.
Is thunder heard before you see lightning?
No, lightning is seen before thunder is heard. The speed of light is faster than the speed of sound, so light from the lightning reaches us first, followed by the sound of thunder a few seconds later.
Why is there a gap between seeing lighting and hearing thunder?
Lightning is a visible phenomenon that travels at the speed of light, while sound from thunder travels much slower at the speed of sound. This difference in speed is why we see the lightning first before hearing the thunder, creating a gap between the two perceptions.
Why do you see lightning before you see thunder in terms of wave theory?
You see lightning first because light travels faster then sound.Also, you don't see thunder - you hear it.
Why do you hear lighting long after you see the flash?
You hear the sound, called thunder, after the flash because light travels many times faster than sound and therefore reaches you first.
Does lighting usually hit you on the first try?
Do you mean you are trying to get hit your question doesn't exactly make sense
Why is it in a thunder storms you see the ligherning before the thunder?
Light travels faster than sound, so you see lightning before you hear the thunder. The lightning flash reaches your eyes almost instantly, while the sound of thunder takes longer to reach your ears because it travels at a slower speed.
