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.
What else can I help you with?
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 concave lens alone to form an image on a screen?
No, a concave lens alone cannot form a real image on a screen. Concave lenses always produce virtual, upright, and diminished images.
Can a concave lens usually produce a real image?
No, a concave lens usually produces only virtual images. This is because the light rays diverge after passing through the lens and cannot converge to 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.
Does a concave lens form a real or virtual image?
A concave lens forms a virtual image of an object located at a distance greater than the focal length of the lens. The image is always upright and reduced in size compared to the object.
Why is real image not formed by concave lens?
A real image is not formed by a concave lens because the light rays passing through a concave lens diverge, rather than converge, making it unable to form a real image. Concave lenses only produce virtual images where the rays appear to diverge from a point behind the lens when extended backwards.
Is it possible for a diverging lens to form a real image Explain?
No, a diverging lens will always form a virtual image. This is because the light rays diverge after passing through the lens, preventing them from actually converging to a real focal point where an image could be formed.
When a pencil is viewed through a concave lens?
The pencil will appear smaller and the image will be upright. The concave lens diverges light rays, causing them to spread out instead of coming together to form a real image.
Does not form a real image?
(1)A plane mirror (2)A convex mirror (3)A concave lens
Which does not form a real image?
(1)A plane mirror (2)A convex mirror (3)A concave lens
Is it possible for a concave lens to for an image on a screen?
Yes, a concave lens can form a real or virtual image on a screen depending on the object position relative to the focal point of the lens. If the object is placed between the lens and its focal point, a virtual image is formed on the same side as the object. If the object is beyond the focal point, a real inverted image can be formed on a screen.
Does a concave lens always produce a virtual image?
No, a concave lens can produce both real and virtual images depending on the object location relative to the lens. If the object is located within the focal point of the concave lens, a virtual image will be produced. If the object is located beyond the focal point, a real image will be formed.
