Why do we see lightning before thunder? | #aumsum

63 Comments



Topic: Light and Sound. Why do we see lightning before thunder? Don’t go out tonight. A huge storm is coming. Look at the weather outside. See, there’s a huge lightning strike. Now, very soon, you are going to hear some thunder. I told you. Don’t get scared. It’s just thunder. Do you know why you saw the lightning before you heard the thunder? I will tell you. An interesting fact is that lightning and
thunder occur at the exact same time. Then why do we see lightning first? This is because light travels faster than
sound. The speed of light is 300 million meters per second while the speed of sound is only 340 meters per second. Thus, the light from the lightning travels
much faster to our eyes. As a result, we first see the lightning, shortly followed by the sound of thunder.
