Place an object between a magnifying lens and its focal point. The image is right side up and larger than the object
the same size right side up and virtual
we can use convex lens(having tapered ends) for that. but the magnifying capability depends on the power the lens. 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 lenght of the lens for this to occur. Otherwise, the image appears smaller and inverted, and can be used to project images onto surfaces.
A converging lens is a simple magnifying glass when the object is within one focal length of the lens. The image is then virtual, magnified, and right-side up.
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length

The magnifying power of a telescope is the focal length of the scope in millimeters, divided by the focal length of the eyepiece in millimeters. Focal length of scope: 225cm=2250mm Focal length of eyepiece: 7.5mm 2250/7.5= 300X

Convex (I prefer converging lenses) lenses are thicker in the middle than at the edges. This causes the rays to converge towards the principle axis (line running through the center of the lens perpendicular to the surface). two images will be formed. When the object you are viewing is farther from the lens than the focal length you will have an inverted real image. This image can be enlarged (when the object is between the focal length and twice the focal length), the same size (when the object is twice the focal length from the lens) or reduced (when the object is beyond twice the focal length). When the object is closer to the lens than the focal length you are using the lense as a magnifying glass and you will have an upright virtual image.

Simply put, convex lenses make things look bigger. That is obviously beneficial in a magnifying glass. Focal length indicates the distance from the lens that something should be to be in the best focus (or not inverted). Therefore, a small focal length is best for magnifying glasses which are typically used to look at things that are very close to you.
