What are reflective mirrors?

A mirror is reflective because it is a glass pane with a special chemical (idk)

The mirror substrate has either a polished silver or aluminum coating to the back .

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...
