As an expert in the field of optics, I'm delighted to delve into the fascinating properties of images formed by plane mirrors. Plane mirrors are a fundamental part of the study of reflection and have been a subject of interest since the early days of physics. The characteristics of the image formed by a plane mirror are quite distinct and can be understood through the principles of geometric optics.

**Step 1: Characteristics of Images in a Plane Mirror (English)**


1. Virtual Image: The most fundamental characteristic of a plane mirror is that it produces a virtual image. A virtual image is one that cannot be projected onto a screen. It appears to be located behind the mirror and is formed by the extensions of the reflected light rays converging. This is in contrast to a real image, which is formed when light rays actually converge and can be captured on a screen.


2. Upright Image: The image formed by a plane mirror is always upright. This means that the orientation of the object is preserved in the image. If an object is standing vertically, its image will also be vertical, and no matter how the object is tilted, the image will always maintain the same orientation as the object.


3. Left-Right Reversal (Flipped Laterally): While the top-to-bottom orientation is preserved, the left-to-right orientation is reversed. This is often described as a mirror image because if you were to write something on a piece of paper and hold it up to a mirror, the writing would appear reversed left to right.


4. Same Distance from the Mirror: The distance from the object to the mirror is equal to the distance from the image to the mirror. This is a direct result of the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This means that the image appears to be the same distance behind the mirror as the object is in front of it.


5. Same Size as the Object: The size of the image is identical to the size of the object. There is no magnification or reduction in size when the image is formed by a plane mirror. This is because the mirror does not alter the physical dimensions of the object; it merely reflects the light in a way that creates the perception of an image.


6. Infinitely Far Behind the Mirror: The image appears to be located at an infinite distance behind the mirror. This is a theoretical concept because, in practice, the image can be focused on a screen if the screen is placed at the same distance from the mirror as the object.

7.
No Parallax: When viewing the image from different angles, there is no parallax. This means that the image does not appear to shift position relative to the mirror as the observer moves. This is a unique property of plane mirrors and is different from the behavior of images formed by lenses or curved mirrors.

8.
No Distortion: Unlike some other types of mirrors, plane mirrors do not distort the image. The straight lines of an object remain straight in the image, and the proportions of the object are maintained.

9.
Symmetrical: The image is symmetrical with respect to the mirror surface. This means that if you were to draw a line perpendicular to the mirror, the object and its image would be mirror images of each other across that line.

10.
Monocular Vision: The image formed by a plane mirror can be seen with one eye only. This is because the image is not a physical object, and the light does not diverge from the mirror as it would from a real object.

In conclusion, plane mirrors produce images with a number of distinguishable characteristics. Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object.
