(C) Calculate the wavelength of a 4.8 eV photon and the de Broglie wavelength of a 4.8 eV electron. If the kinetic energy of the electron then increases by a factor of two, determine its new de Broglie wavelength. 17 marks] (d) Determine how much energy would be released if the rest mass of 100 electrons was converted completely to energy. 3 marks]
