When object is within the focal distance then virtual image is formed. But when the object is placed beyond the focus of the covex lens ie if the distance of the object is more than focal length then real image is formed.
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
Convex lens. Concave lens would give only virtual image for real objects.
A convex lens forms a real image.
Convex lenses form real images and concave lenses form virtual images. But there is one case in which convex lens also forms virtual images. This is when object is placed between Principal Focus "F" and Optical Centre "O"
Convex lens always gives a virtual & diminished image.
In a concave lens the object always forms a virtual image. The convex lens also forms a virtual image.
A convex lense forms only a virtual image.
Convex lens. Concave lens would give only virtual image for real objects.
A convex lens forms a real image.
Convex lenses form real images and concave lenses form virtual images. But there is one case in which convex lens also forms virtual images. This is when object is placed between Principal Focus "F" and Optical Centre "O"
Convex lens always gives a virtual & diminished image.
Convex lens give a virtual & diminished image while concave lens give inverted virtual in rare case & magnified image.
Virtual image
concave lens always forms a virtual image
Only a convex lens forms any kind of real image and the size of the image is dependent upon the focal length (hence the curvature and and substance) of the lens. A concave lens forms a virtual or imaginary image in front of the lens. It is one that cannot be projected onto a surface. Perhaps what you mean has to do with convergence and divergence. A convex lens causes light rays to converge (come together at a point), while a concave lens causes rays to diverge.
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.
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.
