Question

State the expression for lateral magniification of a concave in te terms of object distance and image distance.(mirror/len is not given.)
Also what do ou mean by lateral magnification?​

Answer 1

☆☞ Here is ur answer ☜☆

✔✔ Magnification can be understood in such a way that a negative sign (of m) indicates inverted image and vice-versa.

A real image is always inverted one and a virtual one is always erect.

Thus the real object and its real image would lie on the same sides in case of mirror and on opposite sides in case of lenses, we define m as in case of reflection by spherical mirror as :

✔✔ m = −v/u

Answer 2

۰۪۫H۪۫۰۰۪۫o۪۫۰۰۪۫l۪۫۰۰۪۫a۪۫۰

The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho). The magnification equation is stated as follows:

۰۪۫m۪۫۰= -۰۪۫v۪۫۰/u

These two equations can be combined to yield information about the image distance and image height if the object distance, object height, and focal length are known.
