Question

(02.02r mc) how does the resolution of a specimens image viewed under a compound light microscope compare to that of a scanning electron microscope? the resolution of the image depends on the specimen being viewed, not on the microscope being used. a scanning electron microscope provides much better resolution than a compound light microscope. a compound light microscope provides much better resolution than a scanning electron microscope. the resolution is the same using either microscope; the microscopes differ only in magnification power.

Explanation:

To determine the correct answer, we analyze the resolution capabilities of different microscopes:

• Scanning electron microscopes (SEM) use electrons for imaging, which have much shorter wavelengths than visible light used in compound light microscopes. This allows SEM to achieve much higher resolution (ability to distinguish fine details) compared to compound light microscopes.
• Option 1 is incorrect because resolution depends on the microscope's imaging mechanism (e.g., light vs. electron) and its design, not just the specimen.
• Option 3 is incorrect as compound light microscopes have lower resolution than SEM.
• Option 4 is incorrect because microscopes differ in both magnification and resolution; electron microscopes have better resolution than light microscopes.

Answer:

A. A scanning electron microscope provides much better resolution than a compound light microscope.
