Question

What can one say about the image produced by a thin lens that produces a positive magnification?

Answer 1

Answer:

The image is virtual and upright

Explanation:

The magnification of a lens can be written as follows:

$M=\frac{y'}{y}=-\frac{q}{p}$

where

y' is the size of the image

y is the size of the object

q is the location of the image with respect to the lens

p is the location of the object with respect to the lens

In this situation, the magnification is positive. This means that:

- y' (the image) has same sign as y (the object) --> the image is upright (same orientation as the object)

- q has opposite sign to p --> this means that the image is located on the same side as the object, so it is a virtual image
