QUESTIONS 1. What is resolution "resolving power"? II. um. What does this 2. The resolving power of the compound light microscope is value mean? 3. Define parfocal, and explain the significance of understanding this concept when using the compound light microscope? 4. What is the total magnification of a compound light microscope? 38 MICROSCOPY and instrumentation Part II: MICROSCOPY: Lab Activity 1
Light of 10 cm wavelength is classified as what type of radiation? x-ray microwave UV γ-ray visible
A 1.0-cm-diameter microscope objective has a focal length of 2.8mm . It is used in visible light with a wavelength of 550nm.What is the objective's resolving power if used in air?___nmWhat is the resolving power of the objective if it is used in an oil-immersion microscopewith noil= 1.45?___nm
Define Light Gathering Power, Magnifying Power and Resolving power in your own words. Do the larger diameter telescopes have bigger or smaller resolving power? Explain why this is a good thing. Do the larger diameter telescopes have bigger or smaller magnifying power? Explain why this is a good thing.
how do x-ray absorption and production differ from UV-Vis production and absorption?
. What wavelengths of light (UV, specific colors, infrared, X-ray, etc.) do you expect plants to use for photosynthesis? Which ones would make the most sense and why?
What is x ray scattering? How does scattering affect the contrast of the x ray image? So how does scatteting affected by the x ray voltage and tube current? What is the affect of tube voltage, current, target material and filtration on the x ray tube
What do you mean by resolving power? Write the Rayleigh's criterion for limit of resolution. Derive the expression of resolving power of grating
1 & 2. A is a device placed at x-ray port to absorb low-energy radiation that does not contribute to the diagnostic value of the image and a is a device placed between patient and image receptor to absorb secondary scatter radiation.. 3. Gamma rays have wavelengths that are shorter relative to ultraviolet (UV) rays and would therefore be expected to have Higher or Lower LET values per millimeter of tissue than UV radiation. times greater than 4. In general,...
Calculate the resolving power of a mass spectrometer that gave a mass spectrum with a peak centered at m/z 1141 with a width at the half-height of 0.70 m/z units. resolving power Would you expect this spectrometer to be able to distinguish two peaks found at m/700 and m/2 7017 no yes Would you expect this spectrometer to be able to distinguish two peaks found at m/2 6000 and m/: 6001? yes no
