Magnification enlarges an image, while resolution is the ability to distinguish two close points.
Light microscopy limit about 0.2 ยตm because of the wavelength; empty magnification enlarges without extra detail. Numerical aperture and oil immersion improve resolution.
Resolution depends on wavelength and numerical aperture: d = 0.61ฮป/NA. Electron beams have shorter wavelengths.
Common mistake: zooming in on a blurry image does not improve resolution.
Magnification enlarges an image, while resolution is the ability to distinguish two close points.
Magnification and Resolution is one of the 51 topics in Lab Methods & Biostatistics. It is rated Beginner, so it suits learners who are starting out in biology. Related topics in this area include Light Microscope, Electron Microscopy, Super-Resolution Microscopy.
Ribosomes are too small to see with a light microscope.
Magnification and Resolution is a Beginner topic, so no earlier topic is required. Other Beginner topics in Lab Methods & Biostatistics that pair well with it include Scientific Method, Hypothesis, Variables.

Magnification and Resolution: Magnification enlarges an image, while resolution is the ability to distinguish two close points. Light Microscope: Uses lenses and visible light to magnify specimens up to about 1500 times. Read both side by side and note what each one explains.
Zooming in on a blurry image does not improve resolution.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Light Microscope and explain the difference aloud. Finally, take the Lab Methods & Biostatistics quiz and come back to this page for any question you miss.
