in which medium does sound travel faster.

Sound travels faster in solids compared to liquids and gases. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to transfer more quickly. Here's a step-by-step explanation:

1. Sound travels through the vibration of molecules in a medium. The medium can be a solid, liquid, or gas.

2. In solids, the molecules are tightly packed together. When a vibration occurs, it quickly transfers to the next molecule due to the small distance between them. This allows the sound to travel faster.

3. In liquids, the molecules are not as tightly packed as in solids but are closer together than in gases. So, sound travels slower in liquids than in solids but faster than in gases.

4. In gases, the molecules are far apart. When a vibration occurs, it takes more time to reach the next molecule, making sound travel slowest in gases.

So, the speed of sound is fastest in solids, slower in liquids, and slowest in gases.
