✰Answer ✰

➧ The magnification of an object due to plane mirror is same as that of the object.

✰Extra Knowledge :-

➧ A concave mirror forms an image that is smaller than the object.

➧ The size of the image formed by a concave mirror can be a smaller than, equal to or larger than the size of the object depending on where the object is placed in front of the mirror.

➧ The quantity he/ho (where ho is the object height and he is the image height )is called magnification its magnitude indicate how many times is the size of image as compared to that of the object and its sign indicate whether it is electro inverted positive sign indicates and erect image and negative sign and inverted image.

$m = \frac{he}{ho} = - \frac{v}{u}$

where,

"he" is the image height

"ho" is the object height

✰Note:- The M can be either positive or negative depending on the nature of the image .If m is positive ,ho and he have the same sign. This means that the image is formed on the same side of the principal Axis as the object . In other words the image is erect. If m is negative, the image is inverted.
