Fill in the following blanks with suitable words :
A _________ minor can form a real and inverted image.

Answer

To fill in the blank in the statement "A _________ minor can form a real and inverted image," we need to identify the type of mirror that has the ability to produce such an image.

### Step-by-Step Solution:

1. **Understanding the Types of Mirrors**:
- There are three main types of mirrors: concave mirrors, convex mirrors, and plane mirrors.
- Each type of mirror has different properties regarding the images they form.

2. **Properties of Concave Mirrors**:
- A concave mirror is curved inward, resembling a bowl.
- It can form real and inverted images when the object is placed at a certain distance from the mirror.

3. **Image Formation by Concave Mirrors**:
- When an object is placed at the center of curvature of a concave mirror, the rays of light converge after reflecting off the mirror.
- The image formed is real (it can be projected on a screen) and inverted (upside down) compared to the object.

4. **Comparison with Other Mirrors**:
- **Convex Mirrors**: Always form virtual images that are upright and smaller than the object.
- **Plane Mirrors**: Always form virtual images that are upright and the same size as the object.

5. **Conclusion**:
- Based on the properties and examples discussed, the correct answer to fill in the blank is "concave."

### Final Answer:
A **concave** mirror can form a real and inverted image.
