Simplest Magnifying Device

The simplest magnifying device is a single convex lens. This type of lens is often used in magnifying glasses and reading glasses. It works by bending light rays that pass through it, which magnifies the image. The magnification power of a lens is determined by its focal length. For example, a lens with a focal length of 10 centimeters would have a magnification power of 10/25 or 2, while a lens with a focal length of 3.5 centimeters would have a magnification power of 10/3.5 or approximately 2.86.

In summary, the simplest magnifying device is a single convex lens, which works by bending light rays to magnify the image.
