virtual
The most comon name for this is a mirage. Another such image, differently caused, is called a virtual image.
If you look at something in front of you, light bouncing off that thing enters your eye and you say you can see the object. If now you put a mirror between you and the object, and if you move around you can find a place where you can see it "in the mirror". The object appears to be "through the mirror". The light rays have been bent through angles, but your eye is deceived to believe the object is behind the mirror. It is called a virtual image, because there is nothing to be found at the apparent place where the light appears to come from. That apparent source is called the virtual image. In lenses, the light is bent in such a way that it appears to the eye to come from a place different from the true position of the object. Also a virtual image. Incidentally, when you "see" anything, it is because your eye lens has focused light rays onto your retina. Just like a camera lens focusses onto the image plane (film or sensor chip). That focussed image is a real image. If you look at the sun, it will burn a hole in your retina, the shape of the sun.
this object is called a lens
it is called an image
What is an image?We see objects, because they either emit or reflect light. We visually identify objects by the pattern of light that they emit or reflect. We gather some portion of that light on a detector (our eyes). In interpreting the pattern, we implicitly assume that the light traveled in a straight line from the object to the detector.A real image of an object produces the same pattern of light as the object does somewhere in space. Some portion of the light from the real image reaches our detector along a straight-line path. The detector cannot distinguish between light coming from the object and light coming from the image. We interpret the same patterns in the same way. A virtual image is the apparent position from which a pattern of light reaches our detector, if we make the assumption that it has traveled from its source to the detector along a straight-line path. Virtual images are formed when light from an object or from an image is reflected or bend on the way to the detector DR Amir

You are thinking of a lens. If it is to form an image you need a convex lens, also called a converging lens.

In optics, a virtual image is an image in which the outgoing rays from a point on the object never actually intersect at a visable point. However, if these rays were stretched out they would intersect at a point behind the mirror/surface.
