Assertion : For real objects, image formed by a convex mirror always lies between pole and focus.
Reason : When object moves from pole to infinity, its image will move from pole to focus.

Options

A. (a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. (b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. (c) If Assertion is true, but the Reason is false.
D. (d) If Assertion is false but the Reason is true.

Answer

To solve the question regarding the assertion and reason related to the image formation by a convex mirror, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that for real objects, the image formed by a convex mirror always lies between the pole (P) and the focus (F).
- In a convex mirror, the image formed is always virtual, upright, and diminished, regardless of the position of the object.

2. **Analyzing the Image Formation**:
- When an object is placed in front of a convex mirror, the rays of light diverge after reflecting off the mirror.
- The extensions of these diverging rays appear to meet at a point behind the mirror, which is the virtual image.
- This virtual image is always located between the pole and the focus of the mirror.

3. **Understanding the Reason**:
- The reason states that when the object moves from the pole to infinity, its image will move from the pole to the focus.
- As the object moves closer to the mirror (from a far distance towards the pole), the image also moves closer to the mirror.
- The image will always remain virtual and will approach the focus as the object approaches the mirror.

4. **Conclusion**:
- Both the assertion and the reason are true.
- The reason correctly explains the assertion because it describes the behavior of the image as the object moves closer to the mirror.

5. **Final Answer**:
- Both the assertion and the reason are true, and the reason is the correct explanation of the assertion.
