- An alpha particle reaches 28 fm in a gold foil experiment before it lost all of its kinetic energy. Estimate the kinetic energy of the alpha particleUV light causes sunburn, whereas visible light does not.Suggest a reasonIonizing radiation interacts with matter by scattering from electrons and nuclei in the substances. Based on the law of conservation of momentum and energy, explain why electrons tend to absorb more energy than the nuclei in these interactions.
