Here's why:

* Lens System: Microscopes use multiple lenses to magnify the image. The first lens (objective lens) forms a real, inverted, and magnified image. This image is then further magnified by the second lens (eyepiece).

* Image Formation: The eyepiece acts like a magnifying glass, viewing the inverted image formed by the objective lens. Since the eyepiece doesn't change the orientation of the image, the final image you see through the microscope is still upside down and backwards.

In summary: The combination of the objective and eyepiece lenses in a microscope creates an inverted and reversed image of the object being viewed.
