The electron microscope has been widely used to obtain highly magnified images of biological and other types of materials. When an electron is accelerated through a particular potential field, it attains a speed of 3.60 106 m/s. The mass of the electron is 9.11 x 10-31 kg. Planck's constant has the value h = 6.63 x 10-34 J-s. What is the characteristic wavelength of this electron?
