Question

explain the lense mecor formula ​

Answer 1

The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). ... 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.

Answer 2

Explanation:

A lens is a piece of transparent material, usually circular in shape, with two polished surfaces, either or both of which is curved and may be either convex (bulging) or concave (depressed). The curves are almost always spherical; i.e., the radius of curvature is constant.
