Light travels quicker than sound.
Imagine you're at a fireworks show on a dark night. Boom! A firework explodes in the sky, you see it almost instantly. But the sound of the explosion takes a little longer to reach your ears. That’s because light moves faster than sound does.
Why Light is the Speedy Sprinter
Why Sound is the Slow Pacer
Now imagine your friend is far away, shouting at you across a big field. You see them open their mouth, but the sound takes time to travel through the air until it finally reaches your ears. It's like waiting for a letter in the mail, it takes time to arrive.
So next time you're watching fireworks or hearing someone shout from afar, remember: light is the speedy sprinter, and sound is the slow pacer!
Examples
- When you clap your hands, the sound takes a moment to reach someone across the room.
