The electron microscope uses the wave property of electrons toobserve very small objects. A moving electron has a wavelengthdescribed by the de Broglie equation. What would be the kineticenergy, in J, of an electron with a wavelength of 0.485 nm, whichwould be equivalent to the wavelength of electromagnetic radiationin the X-ray region? (The mass of an electron is 9.11 × 10⁻²⁸g.)
