Answer
The electromagnetic spectrum is divided into seven named regions, each containing a range of wavelengths (or frequencies).
Explanation
The electromagnetic spectrum is a range of all types of electromagnetic radiation. Radiation is energy that travels and spreads out as it goes. The visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The electromagnetic spectrum is divided into seven regions based on wavelength or frequency: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each region contains a range of wavelengths (or frequencies). The spectrum does not have an infinite limit of largest and smallest frequencies; it is finite but extremely broad. The regions do not overlap with each other, and the wavelengths are not equal across different regions. The visible spectrum is only a small part of the electromagnetic spectrum and is divided into colors, but the entire electromagnetic spectrum is not divided into equally sized regions.
