Know the lower limit of resolution for the light microscope Correct Answer-0.2 um Total magnification vs magnification of the oil immersion lens Correct Answer-Total magnification: product of the magnification of the ocular (10x) and the objective lens Oil immersion lens Define Resolving power Correct Answer-the ability of a microscope to differentiate two closelyk spaced objects as being distinct from one another Know how resolving power relates to magnification Correct Answer-Resolvi...

What is the lower limit of resolution with the light microscope? Correct Answer-.2µm Define Parfocal: Correct Answer-A slide in focus will still be in focus to nearly in focus on a different objective. The magnification of the oil immersion objective is: Correct Answer-100x The total magnification of the oil immersion is: Correct Answer-1000x, Product of the magnification of the ocular (10x) and the objective lens (100x). Resolving power: Correct Answer-Ability of a microscope to di...

*magnification of oil immersion lens Correct Answer-100x 1.25 Lower limit of resolution with a light microscope Correct Answer-.2 um What does parfocal mean? Correct Answer-When you have the object in focus with one objective. It will be visible on all objectives with just a minor adjustment from the fine adjustment knob - a specimen in focus under the low power objectives (4x or 10x) should be nearly in focus under the oil immersion objective as well Relationship between resolving po...

Magnification: A. the ability of a microscope lens to distinguish two separate points B. the amount an object is enlarged Answer - B Resolution: A. the ability of a microscope lens to distinguish two separate points B. the amount an object is enlarged Answer - A Most light microscopes carry a ________ light filter Answer - blue Why do light microscopes have a blue light filter? A. to filter out blue light, leaving more red light, which is best for highest resolution images ...
