The total magnification achieved when using a 100× oil immersion lens with 10× binocular eyepieces is a. 10×. b. 100×. c. 200×. d. 1000×. e. 2000×.

Define each of the following terms:  A) What is resolution and how is resolution related to the wavelength of light used to  illuminate the sample?  B) What is the magnification of the specimen if you are using a 40x objective and a 10x  eyepiece?  C) How is the numerical aperture (NA) of a lens related to its ability to gather light from a  specimen?

When using the 10x lens to view a specimen, what is the total magnification of the specimen to the eye? A. 10x B. 100x C. 400x D. 1000x

What is the diameter of the field of view (ie. Diameter2) when the total magnification is 100X? Report your answer in µm

Why do you use immersion oil with 100X objective lens?

Adjusting the objective aperture is an important step to obtain phase contrast in TEM. Compare the differences in objective aperture operation between diffraction contrast and phase contrast.

The numerical aperture of the an objective lens:   indicates magnification   indicates the clarity   indicates light capturing ability   indicates the approprite use

Given the following definitions state the term: A revolving disc which houses the objective lenses A rectangular plate which holds the slides Column above the inclination joint that connects the body tube to the base Contains two circular convex lenses. This magnifies an object usually by 10 times Moves barrel up and down over a large distance which brings the object into general focus

Photoelectric effect increases the _________ in an x-ray image while Compton scattering increases the _________ . Therefore, _________ is not desirable in diagnostic imaging. Select one: a. image noise; radioactivity; photoelectric effect b. image contrast; image noise; Compton scattering c. radioactivity; image noise; Compton scattering d. image noise; image contrast; photoelectric effect
