Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.
In this way, how does radioactivity work for kids?
Radioactive atoms, however, do change over time. Small particles and energy fly out of them naturally. The particles and energy that are released are a form of radiation. The atoms are changed a little bit each time they release something.
Subsequently, what is radiation definition and example? Radiation includes emanation of any portion of the electromagnetic spectrum, plus it includes the release of particles. Examples include: A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles.
Likewise, people ask, why is it called radiation?
The word “radiation” arises from the phenomenon of waves radiating (i.e., traveling outward in all directions) from a source.
