What limits the resolving power of a light microscope?
== == When using a light microscope you encounter diffraction. (Visible light behaves like a wave, with a wavelength of about 300 to 900 nanometres). We say that light diffracts when its wavelike behaviour makes it bend around obstacles, or spread out. If the obstacle is much larger than the wavelength of the incoming wave, the spreading-out will be smaller. If the gap is smaller than the wavelength, then the spreading-out will be very large. In a light microscope, the light waves will spread out whenever they pass through a lens, or any sort of obstruction. The primary lens in most microscopes is of much bigger than 300-900 nanometres, so the angle by which light waves diverge is really quite small. However, it is not zero the light waves do spread out a little bit, and the result is that the visual field is always a bit blurry. It is impossible for an ordinary light microscope to avoid this problem, so they can never see structures smaller than about 500 nm.
How painful is 300 volts?
Rather than just being painful, making contact with a 300 volt power source can be fatal. The severity depends on many factors. Although it thankfully rare, touching a 110V line can kill. In Europe, the mains voltage supply is 230V and more precautions are taken to avoid inadvertent contact than in North America. When those precautions are ignored or bypassed, can be and are killed. Although touching 300 volts is not always fatal, it is wise to assume that it will be. Give it the respect it deserves. Scroll down to related links and look at "Dangerous electricity".
