Answer;
-Adequate magnification,
-Ability to observe cells in the living state,
-Use of wavelength other than the visible spectrum,
-Contrast and resolution
Explanation;
-Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye.
-A microscope is an optical instrument that uses a lens or a combination of lenses to produce magnified images of small objects, especially of objects too small to be seen by the unaided eye.
-Good elements of microscopy includes;
-Magnification (objective lens= forms REAL IMAGE; ocular lens= VIRTUAL IMAGE); total power of magnification is the product of power of both lenses
-Resolution, which is the ability to distinguish two adjacent objects or points from one another
-Good contrast- degree of contrast from its surroundings measured by the refractive index (higher the difference in refractive indexes/bending of light/, the sharper the contrast)
