<em>The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.</em>
The answer is B. X-rays and gamma rays. The electromagnetic spectrum consists of all types of electromagnetic radiation. The EM spectrum is arranged from the longest wavelength with the lowest frequency and lowest energy which are the radio waves and microwaves to the shortest wavelength with the highest frequency and highest energy which are the x-rays and gamma rays. Visible light that can be seen by a humans is a small portion in between the ultraviolet and infrared rays.
