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?

Explanation:
bonjour
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
Explanation:
Ray diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a concave mirror. The use of these diagrams was demonstrated earlier in Lesson 3. Ray diagrams provide useful information about object-image relationships, yet fail to provide the information in a quantitative form. While a ray diagram may help one determine the approximate location and size of the image, it will not provide numerical information about image distance and object size. To obtain this type of numerical information, it is necessary to use the Mirror Equation and the Magnification Equation. The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows:
