* Nature of the Waves: Sound is a mechanical wave, meaning it requires a medium (like air, water, or solids) to travel. It travels by vibrating the particles of the medium. Light, on the other hand, is an electromagnetic wave, which can travel through a vacuum (like space) as well as through matter.

* Speed in Vacuum: The speed of light in a vacuum is approximately 299,792,458 meters per second (186,282 miles per second). Sound needs a medium to travel and its speed varies depending on the medium's density and temperature.

Example: Think about a lightning storm. You see the flash of lightning (light) instantly, but you hear the thunder (sound) a few seconds later. This delay is because light travels much faster than sound.

Here's a quick table to illustrate:

| Wave | Speed in Air (m/s) |

|-------------|-------------------|

| Sound | 343 |

| Light | 299,792,458 |
