The electrons in an electron microscope have speed of 4.7 Mm/s . Part A Find their de Broglie wavelength. Express your answer to two significant figures and include the appropriate units.
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)
What is the magnitude of the momentum of an electron with a de Broglie wavelength of 0.410 nm? O kg.m/s
If an electron, a soccer ball, and a proton all have the same
momentum, which has the shortest de Broglie wavelength?
soccer ball
electron
proton
all have the same wavelength
It depends on the energy of the electron.
