You would like to observe an E. coli bacterium that is 1.95 µm long. Because diffraction blurs an image, you would like to minimize the effects of diffraction by using a wavelength no larger than the object you are observing. For this problem, assume the wavelength is equal to the length of the bacterium. What is the energy of a photon with this wavelength? energy of photon: What is the energy of an electron with a de Broglie wavelength of this size? energy of electron: In terms of energy, which particles, photons or electrons, are the least likely to damage your sensitive biological sample? O photons they are the same electrons J J
