EDUCATIONAL TIP - Why Do We See Lightning Before We Hear Thunder?
You see the flash first, then hear the boom later. It's not that they happen at different times. They happen at the SAME time.
Light travels very, very fast. Almost instantly.
Sound travels much slower.
So the light reaches your eyes first, and the sound reaches your ears seconds later.
That's why you can even count to know how far the storm is. Every 3 seconds between flash and thunder = about 1km away.
Nature is timing itself for you.
