Eli5: My bicycle light warns of radiation if you stare directly at the light. Why isn’t simply touching or being next to it an issue?
In: Physics
The definition of radiation is energy emitted as electromagnetic waves or moving subatomic particles. Many people imagine nuclear radiation when they hear “radiation”, but that isn’t the only kind.
For example, light is radiation. Your bike light is warning you that staring into a bright light can hurt your eyes.
