Detailed Solution

The magnification of an image is taken to be positive. Then, the nature of the image formed is virtual and erect.
The image's height divided by the object's height is known as magnification. When height is measured above the principal axis, it is positive, and when it is measured below the principal axis, it is negative. The positive sign of magnification indicates that the image formed is erect and virtual. Conversely, a real and inverted image is indicated by the negative sign of magnification.
