Sound can travel through

Options

A. gases only
B. solids only
C. liquids only
D. solids,liquids and gases

Answer

**Step-by-Step Solution:**

1. **Understanding Sound Waves**: Sound waves are classified as mechanical waves. This means they require a medium to travel through, unlike electromagnetic waves which can travel through a vacuum.

2. **Identifying the Types of Mediums**: There are three main types of mediums through which sound can travel:
- **Solids**: In solids, sound travels through the vibrations of tightly packed molecules.
- **Liquids**: In liquids, sound travels through the movement of molecules that are less tightly packed than in solids but still close enough to transmit sound.
- **Gases**: In gases, sound travels through the vibrations of molecules that are far apart compared to solids and liquids.

3. **Propagation of Sound**: Sound travels by the propagation of vibrations through the medium. This means that when an object vibrates, it causes the molecules in the surrounding medium to vibrate as well, passing the sound wave along.

4. **Vacuum Condition**: It is important to note that sound cannot travel through a vacuum because there are no molecules to carry the sound waves.

5. **Conclusion**: Therefore, sound can travel through all three types of mediums: solids, liquids, and gases.

6. **Final Answer**: The correct answer is that sound can travel through solids, liquids, and gases.
