Multiple Choice

Light travels ______ than sound.

Explanation:
Light travels faster than sound because light is an electromagnetic wave that can move through empty space, while sound is a mechanical wave that needs a medium like air, water, or solids to pass along vibrations. In air, light moves about 299,792 kilometers per second, while sound travels around 343 meters per second. Since light doesn’t require a medium and moves so much quicker, it is far faster than sound.
