What is the nature of the image formed by a convex lens if the magnification produce by the lens is +3?

AcademicPhysicsNCERTClass 10

If the magnification produced by the lens is $+$3, the image will be virtual and erect, since the magnification has a positive $(+)$ value.

Explanation

If the magnification $m$ has a positive $(+)$ value, the image will be virtual and erect. And, if the magnification $m$ has a negative $(-)$ value, the image will be real and inverted.

Since a convex lens can form virtual images as well as real images, therefore the magnification produced by a convex lens can be either negative $(-)$ or positive $(+)$.

While a concave lens, forms only virtual images, so the magnification produced by a concave lens is always positive $(+)$.

What is the nature of the image formed by a convex lens if the magnification produced by the lens is +3? 

If the magnification produced by the lens is +3, the image will be virtual and erect. It is because if the magnification has a positive value, the image is always virtual and erect.

What is the nature of the image formed by a convex lens if the magnification produced by the lens is, – 0.5?

If the magnification produced by the lens is -0.5, the image will be real and inverted. It is because if the magnification produced by a lens has a negative value, the image is always real and inverted.
