The carbon-14 nucleus decays, releasing an electron and an antineutrino. Suppose the electron is emitted at a speed of 7.9 × 107 m/s. i) Calculate the de Broglie wavelength of the emitted electron. ii) What is the de Broglie wavelength of a positively charged hydrogen atom moving at the same speed?
