Which instrument is used to enlarge small objects for viewing?

• A. Magnifier
• B. Microscope
• C. Endoscope
• D. Telescope

Answer: (B)

To see tiny details, you need an instrument that provides high magnification with good resolution. A microscope is built for this purpose, using at least two lenses—the objective and the eyepiece—to create a greatly enlarged image of a tiny specimen. The objective forms a real, enlarged image that the eyepiece then magnifies further, letting you examine structures that are invisible to the naked eye. This combination lets you study cells, tissues, and microorganisms in detail, with typical magnifications ranging from tens to thousands of times. A magnifier uses a single lens and offers far less magnification, sufficient for simple close-up viewing but not for detailed study of tiny structures. An endoscope is designed to view internal passages of the body or other hollow organs, often with lighting and cameras, but its primary purpose isn’t to enlarge extremely small objects for detailed viewing. A telescope is meant for distant objects, not close-up inspection of small specimens.
