WebNo image is formed. Light rays from the same point on the object will reflect of the mirror and neither converge nor diverge. After reflecting, the light rays are travelling parallel to each other and do not result in the formation of an image. Between P and F Behind mirror Upright/ erect Enlarged (M greater than 1) Virtual WebConcave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object. The closer the object comes to the focal point (without passing it), the bigger the image will be.
