Key Points

  • A microscope magnifies small, nearby objects that the unaided eye cannot resolve.
  • A telescope, by contrast, is used for distant objects — the distinction the distractors are built on.

Additional Information

  • A compound microscope uses two lens systems: the objective near the specimen and the eyepiece near the eye; total magnification is the product of the two.
  • Light microscopes magnify up to about 1,500×, while an electron microscope reaches magnifications in the millions and revealed cell organelles for the first time.
  • The microscope was developed by Zacharias Janssen, and Anton van Leeuwenhoek improved it enough to observe bacteria.
