Answer 2

Answer:

Explanation:

Characteristics of the image form by the plane mirror are:

Since the image form by the plane mirror has magnification is 1 then,

(I). The size of the image form will be the same as the size of the object.

(II). The distance of the image from the mirror will be the same as the distance of the object from the mirror.

(III). The image form will be virtual.

(IV). The image form will be upright.

the position of image related to the position of the object

The image is as far behind the mirror as the object is in front of it i.e, the perpendicular distance of image from the mirror is equal to the perpendicular distance of object from the mirror.
