because light travels much faster than sound, so you see the light from the lightning before you hear the sound from the lightning.

Thunder and lightning happen at approximately the same time, but lightning travels faster than thunder (even though it is moving a supersonic speeds) and thus we see the flash before we hear the thunder.

Light travels faster than the sound. The event that creates thunder and lighting.. is seen first and we hear the thunder with a time lag because of this reason.

It is because light travels faster than sound. Velocity of light is 3 x 10^8 m/s whereas speed of sound is 300 m/s. Thus, light reaches our eyes before we hear the thunder sound.

the speed of light travels faster then sound. That is they can say you see the lightening and count till you hear thunder and that is how far away the storm is....

It's true that light travels faster than sound, but if the thunderstorm is directly overhead, you will have the lightning and thunder simultaneously, so you will not always see lightning before hearing the thunder.

Thunder is the crashing or booming sound produced by rapidly expanding air along the path of the electrical discharge of lightning.
Therefore, lightning always has to be first.

The sound takes 10 sec. to realize your places. If it travels at 730 miles/hr (or 730/3600 miles/secs) the area would be: d = velocity*time = 730 *10 /3600 = seventy 3/36 = 2.0277777 Miles. Regards.

Light travels a lot faster than sound.
Light travels about 600 million miles/hour while sound only travels about 800 miles/hour.
