11. (10 pts) An electron beam, for cancer therapy, was configured by accelerating the electrons to 1.00 x 105 eV kinetic energy. What is the de Broglie wavelength of these electrons, in meters, to three sig. figs.? 12. W/m = (a) (20 pts) Thiosulfate, S203-, is just like sulfate, except that one oxygen atom in sulfate has been substituted by sulfur. Draw one correct Lewis structure for thiosulfate, showing all lone pairs and all formal charges, if different than zero.

An electron beam was configured by accelerating the electrons to 1.00 × 10^5 eV kinetic energy. What is the de Broglie wavelength of these electrons, in meters?
please explain, thank you! The electron beam in a certain electron microscope produces electrons with a kinetic energy of 173 keV. What is the de Broglie wavelength of these electrons (and hence the size of the smallest thing this microcope can "see")? Again, you will need to use relativity. m(+2E-14 m)
Electrons in an electron microscope have a kinetic energy of 6.01 105 eV. (a) Find the de Broglie wavelength of the electrons. (b) Find the ratio of this wavelength to the wavelength of light at the middle of the visible spectrum (550 nm). (c) How many times greater magnification is theoretically possible with this microscope than with a light microscope?
Consider electrons of kinetic energy 5.29 eV and 529 keV. For each electron, find the de Broglie wavelength (in nm), particle speed (in m/s), phase velocity (speed, in m/s), and group velocity (speed, in m/s). nm 5.29 eV electron de Broglie wavelength particle speed phase velocity group velocity m/s m/s m/s 529 keV electron nm de Broglie wavelength particle speed phase velocity group velocity m/s m/s m/s
The kinetic energy of the auger electrons depends on the composition of the surface. The presence of oxygen atoms on the surface results in auger electrons with a kinetic energy of approximately 525 eV . What is the de Broglie wavelength of this electron? [KE = 12mv2; 1 electron volt (eV) = 1.602×10−19J]
