The image formed by a concave spherical mirror,

Options

A. Is always virtual
B. Is always real
C. Is always inverted
D. May be erect

Explanation

To solve the question regarding the image formed by a concave spherical mirror, we will analyze the characteristics of the images produced by such mirrors based on the position of the object relative to the mirror.

### Step-by-Step Solution:

1. **Understanding the Concave Mirror**:
- A concave mirror is a spherical mirror that curves inward. It has a focal point (F) and a center of curvature (C). The principal axis is the line that passes through the center of the mirror and the focal point.

2. **Positioning the Object**:
- The position of the object relative to the mirror is crucial in determining the type of image formed. The object can be placed at various distances from the mirror, such as beyond the center of curvature (C), at C, between C and F, at F, or between F and the mirror.

3. **Image Formation Scenarios**:
- **Object Beyond C**: The image is real, inverted, and smaller than the object.
- **Object at C**: The image is real, inverted, and of the same size as the object.
- **Object Between C and F**: The image is real, inverted, and larger than the object.
- **Object at F**: The image is formed at infinity (the rays are parallel).
- **Object Between F and the Mirror**: The image is virtual, erect, and larger than the object.

4. **Analyzing the Options**:
- The options provided in the question state:
1. Always virtual
2. Not always virtual
3. Always inverted
4. May be erect
- From our analysis, we see that:
- The image is not always virtual; it can be real depending on the object's position.
- The image is not always inverted; it can be erect when the object is placed between F and the mirror.
- Therefore, the correct option is that the image may be erect when the object is placed between the focal point and the mirror.

5. **Conclusion**:
- The correct answer is that the image formed by a concave spherical mirror may be erect, particularly when the object is placed between the focal point and the mirror.
