Both gamma radiation and visible light are electromagnetic radiation and are, in that sense, variants of the same thing. Gamma rays just have much higher frequencies. read more
Gamma rays just have much higher frequencies. Since the energy of a photon increases as its frequency increases, the photons that comprise gamma rays can be much more destructive than those in the visible light frequencies when they interact with matter. read more
Radiation of some types have a mixture of the properties of those in two regions of the spectrum. For example, red light resembles infrared radiation in that it can resonate some chemical bonds. Above infrared in frequency comes visible light. This is the range in which the sun and stars similar to it emit most of their radiation. read more
