Which type of microscope does not use glass lenses or mirrors in order to focus and view a specimen?
a. Electron Microscope
b. Darkfield Microscope
c. Brightfield Microscope
d. Confocal Microscope
e. Phase Contrast Microscope
f. Fluorescent Microscope
Homework Answers
Electron microscope doesnt use any mirror or lenses
here lenses are magnetic field
electrons are light
scatter electrons from samples are dectected in scanning electron microscope
Electrons Passed through sample are detected in transmission electron microscope
resolution is very high than light microscope

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
