Sara is using a magnifying glass to closely examine her stamp collection. why type of lens is found in a magnifying glass?

Convex

Explanation:

The type of lens that is found in a magnifying glass is a convex lens. Convex lenses are those that are thicker at the middle. In the case of the magnifying glass, this causes the lens to produce a magnified (larger) image of an object.  In this type of lens, rays of light that pass through it converge. Moreover, in a magnifying glass, the image that is produced is found on the same side of the lens as the object.

postards have pictures on them, these pictures are things that may never be seen again. the pictures are a part of our history that shows things. because of this many collectors would pay a lot of money for them.
