Which of the following statements are incorrect for spherical mirror.

Options

A. a concave mirror forms only virtual images for any position of real object
B. a convex mirror forms only virtual images for any position of real object
C. a concave mirror forms only a virtual diminished image of an object placed betwwen its pole and the foucs
D. a convex mirror forms a virtual enlarged image of an object if it lies between its pole and the foucs.

Explanation

To determine which statements about spherical mirrors are incorrect, we need to analyze each option systematically.

### Step-by-Step Solution:

1. **Understand the Types of Spherical Mirrors**:
- There are two types of spherical mirrors: concave and convex.
- Concave mirrors can form both real and virtual images depending on the position of the object.
- Convex mirrors always form virtual images.

2. **Evaluate Each Statement**:
- **Option A**: "The concave mirror forms only virtual images at any position for real objects."
- **Analysis**: This statement is incorrect. A concave mirror can form real images when the object is placed beyond the center of curvature. It only forms a virtual image when the object is placed between the focus and the mirror.

- **Option B**: "Convex mirror only forms virtual images for any point."
- **Analysis**: This statement is correct. A convex mirror always forms virtual images regardless of the position of the object.

- **Option C**: "Concave mirror forms only virtual and diminished images for an object placed between the pole and focus."
- **Analysis**: This statement is incorrect. While the image is virtual when the object is placed between the pole and the focus, it is not diminished; it is actually magnified.

- **Option D**: "Convex mirror forms a virtual enlarged image of the object that lies between the focus and the pole."
- **Analysis**: This statement is incorrect. A convex mirror always forms a virtual image, but it is not enlarged; it is diminished.

3. **Conclusion**:
- The incorrect statements are A, C, and D.

### Final Answer:
The incorrect statements for spherical mirrors are:
- Option A
- Option C
- Option D
