Summary

Description
English: The electromagnetic spectrum, a chart of the different types of electromagnetic radiation ordered by increasing frequency. The frequency in hertz is given on the scale at bottom. The most familiar form of electromagnetic radiation is visible light (center), with infrared (IR) and ultraviolet (UV) light on either side. The higher frequencies of EM radiation (right) consisting of x-rays and gamma rays, are types of ionizing radiation. Lower frequency radiation (left), consisting of light, infrared (IR), microwave (MW), Radio Frequency (RF), and extremely low frequency (ELF) are types of non-ionizing radiation.
