Explain electron microscope the electrons generate the image

Reference no: EM13236701

In an electron microscope the electrons generate the image. For one of the scanning electron microscopes in our Central Analytical Facility, the electrons are accelerated to have a kinetic energy of 200,000 eV. Electrons with this kinetic energy have a velocity of 2.67 x 10^8 m/s, almost 90% of the speed of light. What is the wavelength of the electrons traveling at this very high speed?
