1Clarity of an image is calledresolution
2an actual measurement of how far apart two points must be for the microscope to view them as being separate.limit of resolution
3the resolution improves as the limit of resolution is made ....smaller
4the best limit of resolution achieved by a light microscope0.2 um
5Look at formulas on page 143h
6the measure of a lens's ability to capture light coming from the specimen and use it to make the imagenumerical aperture
7a special condenser that is used so only the light reflected off the specimen enters the objectivedark-field microscopy
8this uses special optical components to exploit subtle differences in the refractive indices of water and cytoplasmic components to produce contrastphase contrast microscopy
9this uses a fluorescent dye that emits fluorescence when illuminated with ultraviolet radiationfluorescence microscopy
10assuming that all other variables remain constant, explain why light of shorter wavelengths will produce a clearer image than light of longer wavelengthsa smaller wavelength will allow for a smaller D value. a small D value means better resolution so it would be more clear.
11the NA of the condenser and low-power objective lenses are 1.25 and 0.25. and it has a wavelength of 520 nm.Look at page 150
