An image is only erect when it is a virtual image, therefore virtual images = … WebThe negative sign indicates that the image is real and the positive indicates that the image is virtual. A concave mirror has negative magnification. The height of the image divided by the height of the object determines the magnification of the concave mirror. Therefore, if the image is inverted and real then the magnification will be negative.
