Just as light waves have particle behavior, a moving particle has a wave nature. The faster the particle is moving, the higher its kinetic energy and the shorter its wavelength. The wavelength, A, of a particle of mass m, and moving at velocity v, is given by the de Broglie Part A relation The mass of an electron is 9.11 x 10 31 kg. If the de Broglie wavelength for an electron in a hydrogen atom is 3.31 x 10 10 m, how fast is the electron moving relative to the speed of light? The speed of light is 3.00 x 10 m/s where h = 6.626 x 10 34 J.s is Planck's constant.
