Never. Since the rays coming from a real object will always be diverging. The action of a concave lens is diverging action. Hence the already diverged rays will be dirverged further. Hence no chance of convergence. Only converging rays would form a real image. Hence the answer, NEVER.

∙ 13y agoYes concave lens can produce a real image. When?
Suppose rays falling on a concave lens are converging one. Then after refraction through the concave lens, the real image is formed. Because already the converging rays would have formed a real image. But because of the interruption of the concave lens, the image that too real will be formed some how at a far distance from the concave lens.
So a learner must learn this way. Any convex lens will make the converging action.
Same way any concave lens would have a diverging action. So already converging rays would be a little bit diverged but yet to be converged. So in such case a concave lens could produce a real image.

∙ 11y agoYes it is possible if rays from a virtual object falls on its surface. That means as converging rays fall on the convex surface then after reflection they would converge at a point and form a real image.

What kind of lens can be used to produce a virtual image?
Convex lens produces both real and virtual images. But concave lens produces only virtual images for real objects. If object is virtual then real image could be produced by a concave lens.
What is an optical device that uses a lens to produce a larger and virtual image?
A camera, television, lap top, glasses, psp, claw machine.
Which lens always produces an image that is upright?
Concave lens (diverging) produces an upright image that is virtual. Although to create a real upright image would require 2 convex (converging) lens with a distance of their respective focal lengths between them.
Does concave lens produce a real image?
Because when you extend the light rays, they diverge and never meet. so you must always extend the light rays back behind the object, this will always result in the image being upright and erect. Meaning it will always be virtual, never real.
What devices use lenses to produce a real image?
Convex lenses are used for glasses since it can bend light to provide better eyesight. Their also used for cameras, telescopes or science purposes. Also you have double convex lens in your eye.
Which lens does not form a real image?
concave lens does not form a rel image and convex MIRROR does not form a real image
Is it possible for a diverging lens to form a real image Explain?
No, it is not possible for a diverging or a concave lens to form a real image. It always forms virtual and erect image
What kind of lens can be used to produce a virtual image?
Convex lens produces both real and virtual images. But concave lens produces only virtual images for real objects. If object is virtual then real image could be produced by a concave lens.
What are the Lens that can create a real or virtual image?
Convex lens. Concave lens would give only virtual image for real objects.
Which does not form a real image?
(1)A plane mirror (2)A convex mirror (3)A concave lens
Does not form a real image?
(1)A plane mirror (2)A convex mirror (3)A concave lens
How do convex and concave lenses affect the attitude and appearance of an image?
Convex lens is a converging lens It makes the image real and inverted whereas concave lens is a diverging lens it makes the image virtual and erect.
Which type of image formed by concave mirror?
A concave mirror forms a virtual, magnified, right side up image.
What image does a concave lens produce?
real or virtual imagevirtual,erect anddiminished
Why is real image not formed by concave lens?
how spores of mosses differ from spores of liverworts
How concave lens produce real image for virtual object?
As it produces images which are reflected in a surface.
What is concave len explain in detail?
In case of concave lens the edges will be thicker compared to the central part. Whereas the convex lens has edges so thin compared to the central part. Concave lens would have only divergence effect. Parallel beam of light falling on one side of the concave lens after refraction would come out from the other side diverging out and so they appear to come from a point on the incident side of lens. So no real image is obtained. Thus the image will be a virtual image. If converging rays fall on the concave lens after refraction may be still converging but it convergence will be reduced a little bit and so instead forming a real image nearby the concave lens it will be formed somehow far away from the lens.
