Is it true a concave lens usually produces real images?
No, a concave lens usually produces virtual images. Real images are typically produced by convex lenses when the object is beyond the lens' focal point. Concave lenses diverge light rays and form virtual images that do not converge at a point.
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.
What optical devices can form real images?
Some optical devices that can form real images include concave lenses, convex lenses, and curved mirrors. These devices can focus light rays to create a real image that can be projected onto a screen.
How do images formed by a concave lens and convex mirror different?
Images formed by a concave lens are always virtual, upright, and reduced in size. On the other hand, images formed by a convex mirror are virtual, erect, and diminished in size. Additionally, concave lenses can form both real and virtual images depending on the object distance, while convex mirrors only produce virtual images.
Do near sighted people wear concave or convex lenses?
Near sighted people wear concave lenses to correct their vision. These lenses help to diverge light rays before they reach the eye, which helps to focus the images properly on the retina.
Similarity between convex lens and concave lens?
they are both lenses and form images
Is it true a concave lens usually produces real images?

does a concave lens usually produces real images?
Convex(converging) lenses can form either real or virtual images.
Do concave lenses focus images?
Not on their own.
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.
What Lenses Always Produce Smaller Images.?
Concave and Diverging
What optical devices can form real images?
Some optical devices that can form real images include concave lenses, convex lenses, and curved mirrors. These devices can focus light rays to create a real image that can be projected onto a screen.
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 the main purpose of object lenses concave mirrors in the telescope?
Magnify images
How do images formed by a concave lens and convex mirror different?
Images formed by a concave lens are always virtual, upright, and reduced in size. On the other hand, images formed by a convex mirror are virtual, erect, and diminished in size. Additionally, concave lenses can form both real and virtual images depending on the object distance, while convex mirrors only produce virtual images.
Do near sighted people wear concave or convex lenses?
Near sighted people wear concave lenses to correct their vision. These lenses help to diverge light rays before they reach the eye, which helps to focus the images properly on the retina.
Do concave lenses always produce a smaller image?
Concave lenses can produce either smaller or larger images, depending on the object's distance from the lens and the characteristics of the lens itself. The image produced by a concave lens can be virtual, upright, and smaller, or it can be real, inverted, and larger.
