Question

The magnification of image produced by a cancave lens is always less than 1 . why?​

Answer 1

Answer:

It is because the image formed by a concave mirror is always smaller than the size of the object.

Answer 2

Explanation:

For a concave lens, the “magnification” is always less than 1. In other words, the image is actually smaller than the object. The distance of a virtual image is very hard to gauge. So calculating magnification from object and image distances may not be accurate.
