Write three characteristics of the image formed by a plane mirror.

Explanation

### Step-by-Step Solution:

1. **Erect and Same Size**:
- The image formed by a plane mirror is erect, meaning it maintains the same orientation as the object. For instance, if the object is upright, the image will also be upright. Additionally, the size of the image is the same as that of the object. If the object is 5 cm tall, the image will also be 5 cm tall.

2. **Virtual Image**:
- The image formed by a plane mirror is virtual. This means that the rays of light do not actually converge to form the image. Instead, the image appears to be located behind the mirror. To visualize this, you would have to extend the reflected rays backward until they appear to intersect.
