You want to use a microscope to study the structure of a mitochondrion about 1.00 um in size. To be able to observe small details within the mitochondrion, you want to use a wavelength of 0.0500 nm. If your microscope uses light of this wavelength, what is the momentum p of a photon? p = kg-m/s If your microscope uses light of this wavelength, what is the energy E of a photon? E = If instead your microscope uses electrons of this de Broglie wavelength, what is the momentum pe of an electron? Pe = kg-m/s If instead your microscope uses electrons of this de Broglie wavelength, what is the velocity v of an electron? v = m/s If instead your microscope uses electrons of this de Broglie wavelength, what is the kinetic energy K of an electron? K = What advantage do your calculations suggest electrons have compared to photons? O An electron's charge allows it to attach to observed particles, whereas a photon's electric neutrality prevents it from moving close enough to the observed particles to keep them in focus. O To obtain the same level of resolution, electrons require multiple orders of magnitude less energy than do photons. O Using photons with a microscope distorts the image due to the relativistic effect of length contraction, whereas using electrons does not shrink the image, because their speed is only about a tenth the speed of light. O Electrons can provide a clearer image than photons at the same magnification because their momenta impact observed particles less than photons' momenta.
