What is linear magnification produced by a lens? How is it related to object distance and image distance?

Text Solution

Verified by Experts

Linear magnifiaction produced by a lens is the ration of size of image `(h_(2))` to the size of the object `(h_(1))`. It is represented by m,
where `m=(h_(2))/(h_(1))=(v)/(u)`.
