Answer:

How did Anton Van Leeuwenhoek able to make a compound microscope?

Anton van Leeuwenhoek learned to grind lenses, and used these to make very simple hand-held microscopes. These microscopes were not compound microscopes made of two or more lenses but refined magnifying glasses made with finely ground lenses. These microscopes, with appropriate lighting, allowed him to magnify objects over 275 times. His curiosity about this microscopic world and his diligence in recording his observations allowed him to share with others what he had seen with his microscopes.

Answer:

Van Leeunwenhoek would place the middle of the glass rod in flame and gradually pull it apart as it melted. This resulted in two separate glass rods tapering to fine points. He then inserted the tiny point of one of the rods into the fire and that created a small glass sphere on its end.

Explanation:

Whereas Van Leeunwenhoek used a simple microscope, in which light is passed through just one lens, Galileo's compound microscope was more sophisticated, passing light through two sets of lenses. The first compound microscopes date to 1590, but it was the Dutch Antony Van Leeuwenhoek in the mid-seventeenth century who first used them to make discoveries.
