What kind of lens and what conditions must be met for the lens to be considered a magnifying glass?

1. converging lens and the light must be shone before the focal length
2. A magnifying glass is two convex lens which are used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle . A magnifying glass works by creating a magnified virtual image of an object behind the lens. The distance between the lens and the object must be shorter than the focal length of the lens for this to occur. Otherwise, the image appears smaller and inverted, and can be used to project images onto surfaces. The framed lens may be mounted on a stand, keeping the lens at the right distance from the table, and therefore at the right distance from the object on the table. The latter applies if the object is small, and also if the height is adjustable. Some magnifying glasses are foldable (from the handle or stand).
3. 1)The most Important condition is dat it must b a convex lens 2)U must place the Object in front of Radius Of Curvature 3)U must Place ur Eyes infront of Focus
4. Any type of transparent solid that is thicker in the center than at the edges will cause the light to converge ,and magnify. if you confine a transparent liquid into the same configuration it will also magnify,oil or water.
