(#11) The electron microscope uses a beam of electrons, instead of a beam of light, to diffract off the specimen in obtaining an image of it. In the umbra no direct light arrives, whereas in the penum-bra the light source is only partially occluded. What makes resolution “too low” or “too high” depends upon the particular application, and what information is desired from the experiment. Shadows do not remain black, they dissipate, creating halftones and obscuring those places in space that get less light.Reduced additional punctual light shadows resolution.
