| transverse wave | A reaction involving the particles in the nucleus of an atom that can change one element into another element. |
| wavelength | An atom with the same number of protons and different number of neutrons from other atoms of the same element. |
| frequency | The sum of the protons and neutrons in the nucleus of an atom. |
| speed | The process in which the atomic nuclei of unstable isotopes release fast-moving particles and energy. |
| amplitude | Particles and energy produced during radioactive decay. |
| crest | A form of nuclear radiation consisting of two protons and two neutrons. |
| trough | An electron that is given off by a nucleus during radioactive decay. |
| Visible light | A form of nuclear radiation consisting of high-energy waves. |
| Radiant energy | The length of time needed for half the atoms of a radioactive isotope sample to decay. |
| frequency | The process of determining the age of an object using the half-life of one or more radioactive isotopes. |
| reflection | A radioactive isotope that can be followed through the steps of a chemical reaction or industrial process. |
| refraction | A process in which radioactive elements are used to destroy unhealthy cells. |
