Options

A. interference of sound
B. reflection of sound
C. diffraction of sound
D. refraction of sound

Answer

To solve the question, "The conversation going on in some room can be heard by the person outside the room, the reason for it is," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Scenario**:
- We have a room where a conversation is taking place. There is a barrier (like a wall) and possibly a small opening (like a hole or a gap) through which sound can travel.

2. **Identifying the Phenomenon**:
- The key phenomenon that allows sound to travel from inside the room to outside is the ability of sound waves to bend around obstacles or through openings.

3. **Defining Diffraction**:
- This bending of waves is known as diffraction. Diffraction occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength.

4. **Applying the Concept**:
- In this case, the sound waves produced by the conversation inside the room can bend around the edges of the opening or through the small hole. This allows the sound to reach the person outside the room.

5. **Conclusion**:
- Therefore, the reason the person outside can hear the conversation is due to the diffraction of sound waves.

### Final Answer:
The reason the conversation going on in some room can be heard by the person outside the room is due to the diffraction of sound.
