What is the name of the phenomenon due to which the right side of an object appears to be left side of the image in a plane mirror ?

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the name of the phenomenon that causes the right side of an object to appear as the left side in its image when viewed in a plane mirror.

2. **Identifying the Phenomenon**: The phenomenon that describes this behavior is known as "lateral inversion." This means that the image produced by a plane mirror flips the object horizontally.

3. **Visualizing the Concept**: To illustrate lateral inversion, consider an object with two points labeled A (left) and B (right). When this object is placed in front of a plane mirror, the image will show B on the left side and A on the right side.
