Question

Expressions of magnification in mirrors

Answer 1

Answer:

The linear magnification produced by a spherical mirror is equal to the ratio of the distance of the image from the pole of themirror (v) to the distance of the object from the pole of the mirror (u) with a minus sign.

Answer 2

Explanation :

Linear magnification or transverse magnification is defined as the ratio of the height of the image to the height of the object.

Therefore, linear magnification in terms of u and f can be expressed using the mirror formula. Thus, we have. Linear magnification in terms of v and f is also found using the mirror formula .
