Final answer:
Light of all types, from radio waves to gamma rays, is called electromagnetic radiation, covering a spectrum of varying wavelengths and energy levels.
Step-by-step explanation:
The term for light of all types, from radio waves through gamma rays, is electromagnetic radiation. Electromagnetic radiation spans a wide spectrum and includes, in order of increasing wavelength, types like gamma rays, x-rays, ultraviolet (UV rays), visible light, infrared (IR radiation), microwaves, and radio waves. Photons characterize each type of electromagnetic radiation and they have different amounts of energy which are inversely proportional to their wavelengths—shorter wavelengths mean higher frequency and more energy.
