What device uses a lens to magnify an image?

• A. Telescope
• B. Camera
• C. Microscope
• D. Projector

Answer: (C)

A microscope is specifically designed to use lenses to magnify small objects, allowing for detailed observation of structures that are not visible to the naked eye. It typically employs multiple lenses, including an objective lens and an eyepiece, to achieve significant magnification and resolution of tiny specimens, such as cells and microorganisms.

While a telescope, camera, and projector also utilize lenses, their primary functions differ from that of a microscope. A telescope magnifies distant celestial objects, a camera captures images, and a projector displays images onto a larger surface. Each of these devices incorporates lenses but for purposes unrelated to examining small samples in detail, which is the hallmark of a microscope's function. Thus, the characteristics and intended use of the microscope make it the correct choice for a device that primarily focuses on magnifying images of small objects.
