Quantized and total photon energy The particle characteristics of electromagnetic radiation are responsible for the quantized behavior of light energy. This behavior explains the results of varying the intensity and wavelength for an observed photoelectric effect, which describes the emission of electrons when light shines on a metal surface. If light only exhibited a purely wavelike behavior, then either increasing the intensity or decreasing the wavelength would both increase the rate at which electron are emitted. However, monochromatic light of...

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...
