DedPeter [7]

Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.
