Question

Which of the following is not a feature of a plane mirror image?

• A. The size of the image is bigger than the object.
• B. The final image obtained is erect.
• C. The image has a lateral inversion.
• D. The image obtained is virtual.

Answer 1

The correct option is A

The size of the image is bigger than the object.

The explanation for the correct option:

In the case of option A,

1. In the plane mirror image, the object's size and the image's size are the same.
2. If the size of the image is bigger than the object then it is called the magnified image and it is not the property of a plane mirror image.

The explanation for the incorrect options:

In the case of option B,

The picture that appears in the mirror when we stand in front of it is a common example of a virtual image. They are always erect because a virtual image is produced above the primary axis.

In the case of option C,

In a plane mirror, the image is as far behind the mirror as the object is in front of it, and the fronts of the image and the object face one another, which causes lateral inversion.

In the case of option D,

The image in a plane mirror will be the same size as the object and will be placed at the same distance from the mirror as the object is in front of it. Because light doesn't truly pass through the image, it is known as a virtual image.

Hence, option (A) is the correct answer.
