Lens A that is Convex lens will form virtual, magnified image when object is placed at 8cm ( in between Optic centre and Focus) WebLenses serve to refract light at each boundary. As a ray of light enters a lens, it is refracted; and as the same ray of light exits the lens, it is refracted again. The net effect of the refraction of light at these two boundaries is that the light ray has changed directions. Because of the special geometric shape of a lens, the light rays are ...

WebThe position of eyepiece is kept such that the image formed by objective lens is formed within the focal length of the eyepiece. Hence, it forms a virtual and magnified image. This is similar to the working of a simple microscope which is also a convex lens and forms a virtual and erect image. WebLenses. Lenses form images by refraction and are typically made of either glass or plastic. They are ground so that their surfaces are either segments of spheres or planes. If a lens is convex or converging, it takes parallel light rays from a distant object and bends them so that they converge to a single point called the focal point.

WebApr 3, 2024 · The concave type of lens always forms a virtual image. The image formed by a concave lens is virtual, upright, and diminished. The image is formed between the object and lens.
