Question

A magnifying glass is what kind of lens, and where do where should I place the lens relative to the object to see an image larger than the object and right-side-up? (“F” stands for focal length of the lens).

Answer 1

Hint: A magnifying glass is a convex lens used to make an object appear much larger than it.
Magnification (m) of a lens is the power of the lens to magnify the image of an object. Magnification of lens is expressed in the ratio of the height Y of the image to the height X of the object. Mathematically, \[m = \dfrac{Y}{X}\]
A convex lens is a lens which is thicker at the center and thinner at the edge, these types of lenses can converge a beam of light coming out from outside and focus it to a point on the other side.


Complete step by step answer:
A magnifying glass has a convex lens is used to make look objects bigger and this works when the object is places at a distance less than focal length.

If an object is placed between the pole and the focus of the convex lens then the lens forms a virtual and erect and enlarged image of the object.
Hence we can say object need to be placed between the pole and the focus.

Note: If the height of the image produced by the lens is more than the height of the object, then the magnification of the lens is positive, and when the height of the image produced is less than the object height, then its magnification is negative.
