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 wavelength, in m, of an electron with a kinetic energy of 4.72 × 10⁻¹⁹ J, which would be equivalent to the energy of a photon in the visible region? (The mass of an electron is 9.11 × 10⁻²⁸ g.)
