Magnification produced by a plane mirror is +1. It means:A. Image formed by a plane mirror is greater than the size of the objectB. Image formed by the plane mirror is erect and of same size as of the objectC. Image formed by the plane mirror is smaller than the size of the object and is virtualD. None

The magnification produced by a plane mirror is +1. Magnification is defined as the ratio of the image height to the object height. In the case of a plane mirror, the image formed is always of the same size as the object, upright (erect), and virtual (it appears behind the mirror).

Let’s break down the choices:

A. Image formed by a plane mirror is greater than the size of the object - This is incorrect. The image size is not greater than the object size.

B. Image formed by the plane mirror is erect and of same size as of the object - This is correct. The image is virtual, upright, and of the same size as the object.

C. Image formed by the plane mirror is smaller than the size of the object and is virtual - This is incorrect. The image is not smaller than the object, and it is virtual.

D. None - This is incorrect because option B is the correct answer.

The correct answer is: B. Image formed by the plane mirror is erect and of same size as of the object.
