A radioactive isotope of cobalt emits a photon of wavelength 9.30 x 10^-12 m. The cobalt nucleus contains 27 protons and 33 neutrons. The cobalt nucleus is in a crystal containing 6.02 x 10¹⁷ identical atoms. Calculate the extremely slow recoil velocity of the cobalt crystal. (1.18 x 10^-15 m/s bd)

Answer rating: 100% (QA)

To calculate the extremely slow recoil velocity of the cobalt crystal we can use the formula for recoil velocity in terms of wavelength The recoil vel... View the full answer
