Why do you hear lightning before you hear thunder?
you dont see thunder you hear it! and you dont hear lightning you see it! GET YOUR FACTS STRAIT! ok so light waves travel fasyer than sound waves
One cannot hear lightning. The sound that lightning causes is the the thunder. You can see the flash of lightning before you hear the sound because light travels much faster than sound. Sometimes the lightning is obscured by the clouds so you do not see the flash but you hear the sound , so you might think you heard the sound first.
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…
Generally, yes. Lighting and thunder originate at the same time, but since light travels much faster than sound, you see the lightning before you hear the thunder. The one exception is if the lighting strikes very close, within a few hundred feet. In this case you see the lightning and hear the thunder at essentially the same time.
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.
The speed of light is faster than the speed of sound. So when lightning occurs, you can see it sooner than you then hear it. The further away you are from the lightning, the longer it takes for you to hear it. If lightning occurs right near you, you see the flash and hear the thunder at the same time.
