Select the elements necessary for good microscopy. check all that apply adequate magnification adequate magnification ability to observe cells in the living state ability to observe cells in the living state use of wavelengths other than the visible spectrum use of wavelengths other than the visible spectrum contrast contrast resolution resolution specimen holder specimen holder

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)

the answer is b: 1.4 km/hr
