A PET scan detects the product of positron electron annihilation. A positron and an electron annihilate and create 2 photons. (a) The wavelength of the photons will not be the same as the deBroglie wavelength of the positron and electron. Explain why. (b) The positron and electron each have a kinetic energy of 60 keV. What is the wavelength of each photon?
