In the context of plane mirror, consider the following assertions — 1...
Assertion 1: An image formed by a plane mirror is erect and of the same size as the object.
When an object is placed in front of a plane mirror, the mirror reflects the light rays coming from the object and forms an image. The image formed by a plane mirror has the following characteristics:
1. Erect: The image formed by a plane mirror is always erect, meaning it appears in the same orientation as the object. This is because the light rays reflected by the mirror do not cross over each other.
2. Same size: The image formed by a plane mirror is of the same size as the object. This is because the distance between the mirror and the object is the same as the distance between the mirror and the image. The image appears to be a virtual replica of the object, maintaining its size.
Therefore, Assertion 1 is correct.
Assertion 2: In the image formed by a plane mirror, the ‘right’ appears ‘left’ and the ‘left’ appears ‘right’.
When we observe an object and its image in a plane mirror, there is an apparent reversal of left and right. This phenomenon is known as lateral inversion. However, it is important to note that there is no actual physical reversal of the object or the image.
For example, if we raise our right hand in front of a plane mirror, the image formed in the mirror appears to raise its left hand. Similarly, if we wear a T-shirt with the word "UP" written on it, the image in the mirror appears to show "PU". This lateral inversion occurs because light reflects from the mirror surface and reverses the orientation of the image in the left-right direction.
Therefore, Assertion 2 is correct.
Conclusion:
Both Assertion 1 and Assertion 2 are correct.
In summary, when an object is placed in front of a plane mirror, the image formed is erect and of the same size as the object. Additionally, the image shows lateral inversion, where the right side of the object appears as the left side in the image, and vice versa.

Community Answer
In the context of plane mirror, consider the following assertions — 1...
- Plane mirrors are simply flat mirrors without curves. Because these can be found almost anywhere, the average person is incredibly familiar with them (even if they don't know the technical term).
- While the first manmade mirrors were made from intensely polished bronze, silver and other metals, today most mirrors are made from glass sheets finished with a thin layer of aluminum.
- That said, plane mirrors can be made from liquid as well: Gallium and mercury can be used for this purpose. Regardless of material construction, however, all flat mirrors function the same way.
- They reflect rays of light, producing an image. Characteristics of the image formed by a plane mirror : • It is virtual • It is erect and of same size as the object • The distance of an object from the plane mirror is the same as the distance of image from the plane mirror.
- One of the important characteristics of the image is that it is laterally inverted. It means if you raise your left hand it would appear in the plane mirror that you have raised your right hand.
