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.

∙ 14y agobecause the light rays never meet, a concave lens can produce only a virtual image.
Wiki User
∙ 13y agoNo, concave lenses always produce virtual, diminished, and erect images.
Wiki User
∙ 10y agoBecause the light rays spread out & never meet the focal point
Wiki User
∙ 13y agoYes, because it cannot reflect light.

∙ 11y agono it can only form virtual image

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.
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.
Can a concave lens form a real image?
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.
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.
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.
What are the Lens that can create a real or virtual image?
Convex lens. Concave lens would give only virtual image for real objects.
What image does a concave lens produce?
real or virtual imagevirtual,erect anddiminished
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.
How concave lens produce real image for virtual object?
As it produces images which are reflected in a surface.
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.
Can a concave lens form a real image?
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.
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
Does convex lens produce real image?
No, convex lens does not produce a real image. It reflects the real image
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.
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
Why a convex mirror and a concave lens can never produce a real image?
Because the light rays spread out & never meet the focal point
Compare the image formed by a concave lens and the image formed by a convex mirror?
the image formed by convex lens are real but the images formed by concave lens are virtual concave mirror are commonly used in to torches search light and vehicles headlights to get powerful parallel beam of light they are often used as a wing a to see a larger image of the face the dentist use a concave mirrors to see larger image of that is open send large can give are used to concentrate sunlight to produce heat in solar furnace
