Resolution is the ability of an optical instrument to..
Magnify the image of an object up to 20 times its actual size.
Penetrate a sample with varying light intensities in order for the viewer to see the image more brightly.
Produce an image that represents fine detail in high clarity and definition.
Label the light microscope.
Select the statement which correctly describes the relationship between magnification, image size, and actual size.
Magnification = image size x actual size
Image size = magnification x actual size
Actual size = magnification x image size
microscopes work by scanning an object with very high resolution using a laser beam, which is analysed by a computer to form an . While expensive, these microscopes produce high r, high c images that can also be -dimensional.
microscopes emit a wavelength of radiation of about nanometers, resulting in a very high . They are also able to images much more than other types of microscope. During the process, are 'spat out' by a . Instead of a glass lens to focus the image in other types of microscope, the microscope uses a . When the electrons reach the sample, some pass it and some bounce off, depending on whether the microscope is (SEM) or (TEM).
