Understanding Plane Mirrors
Plane mirrors do not form inverted images, but it's essential to understand the characteristics of images formed by mirrors in general.

Types of Mirrors
- **Plane Mirrors**: Flat surfaces that reflect light. The image formed is virtual, upright, and of the same size as the object.
- **Concave Mirrors**: Curved inward. They can form real and inverted images when the object is placed beyond the focal point.
- **Convex Mirrors**: Curved outward. They always produce virtual, upright, and diminished images regardless of the object's distance.

Mirror Formula
The mirror formula relates the object distance (u), image distance (v), and focal length (f) as follows:
- **Formula**: 1/f = 1/v + 1/u
Where:
- f = focal length (positive for concave, negative for convex)
- u = object distance (always negative in mirror conventions)
- v = image distance (positive for real images, negative for virtual images)

Magnification
Magnification (m) refers to the ratio of the height of the image (h') to the height of the object (h):
- **Formula**: m = h'/h = -v/u
Where:
- m > 1: Image is enlarged
- m < 1:="" image="" is="" />
- m = -1: Image is the same size but inverted (only occurs with concave mirrors)

Conclusion
In summary, plane mirrors create virtual, upright images, while concave mirrors can form inverted images based on the object's position relative to the focal point. Understanding these principles is crucial in optics.
