1. Under what condition does a concave mirror from a virtual image? Describe the characteristics of this image. - Like convex spherical mirrors, the focus is on spherical concave mirrors. The ima ge will be virtual if the object is closer to the mirror than the focal point is. Concav e mirrors can have virtual on the other side. If the object is further away than the focal point from the mirror, the image will be upside-down and true, which implies the image will appear on the same side of the mirror as the object. The nearer the object (without passing it) comes to the focal point, the larger the image will be
