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