In the sign convention for magnification, a concave lens produces a negative magnification, indicating that the image is virtual, upright, and smaller than the object. Conversely, a convex lens can produce either positive or negative magnification depending on the object's position; it yields a positive magnification for real and inverted images when the object is beyond the focal point and a negative magnification for virtual and upright images when the object is within the focal length.

Is a microscope convex or a concave?
A microscope typically uses a convex lens to focus light and magnify an image. The convex lens converges light rays to produce a magnified image, whereas a concave lens would diverge light rays and not be suitable for magnification in a microscope.

What lens is a converging lens double-convex spherical-convex plano-concave or convexo-concave lens?
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
What do convex and concave lens do?
A convex lens converges light rays to a focal point, used to correct hyperopia (farsightedness) or create magnification in optical devices. A concave lens diverges light rays, used to correct myopia (nearsightedness) or reduce image size in optical systems.
What is Another name of convex and concave lens?
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
When does a concave lens act as convex lens?
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .

What is a convex and a concave lens?
CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.
