*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...

Chapter 1: microbial cell structure and function CORRECT ANSWER Microscopy: compound microscope CORRECT ANSWER •Compound microscope -- Two sets of lenses form the image (Figure 1.15a) •Objective lens and ocular lens Microscopy: magnification CORRECT ANSWER •Total magnification = objective magnification ocular magnification • •Magnification: the ability to make an object larger Microscopy: resolution CORRECT ANSWER •Resolution: the ability to distinguish two adjacent obj...

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...

SEMMELWEIS UNIVERSITY, MEDICAL BIOPHYSICS - FINAL EXAM UPDATED Exam Questions and CORRECT Answers Coulter principle. - CORRECT ANSWER- The ability to count and measure the size of particles using an electric circuit. Particles are moved through a small aperture, their presence causes a narrowing of the aperture, which leads to an increase in resistance.By using constant I, According to Ohms law (U= I * R), when R increases, U increases and pulse is generated

Gantry Contains the x-ray tube and detectors Includes 80-90-cm aperture for patient Section The same as "slice" or "cut" xray tube source of xrays reference detector used to monitor the incident beam power Collimator Restricts the size and shape of the x-ray beam
