The electromagnetic spectrum is a group of different types of waves, which include radio waves, light, X-rays and gamma rays. The electromagnetic spectrum can be divided into seven different categories: radio waves, infrared light, visible light, ultraviolet light, X-rays and gamma rays.
The characteristics of electromagnetic waves include their wavelength, frequency, and amplitude. The wavelength is the distance between two adjacent points on the waveform--the higher the frequency, the shorter its wavelength will be. The frequency is determined by how many times per second a wave repeats itself; thus, higher frequencies have shorter wavelengths than lower ones. The amplitude of an electromagnetic wave refers to how much energy it carries at any given time--a low amplitude means little energy is being carried by the waveform while a high amplitude means more energy is being carried by it.
Electromagnetic waves vary widely in their properties depending on what they're traveling through: radio waves travel through air easily while infrared radiation requires lots of glass or plastic to pass through without getting absorbed by other molecules or atoms along its path through space; visible light travels through air easily but not glass or plastic; ultraviolet light requires special filters for safe passage through glass or plastic but not air; gamma rays don't pass through anything except possibly lead (which absorbs them nicely), so they're very dangerous if you ever encounter one (but
Radio waves are the lowest frequency electromagnetic wave and have wavelengths between 1m and 1mm. They travel through air easily and are used in short range communication systems like cell phones or Wi-Fi networks.
Infrared light has wavelengths between 0.7mm and 1mm and is invisible to the human eye because it cannot be seen by heat vision; however, it can be detected by other means such as heat sensors on your computer screen or mobile device's camera lens.
Visible light has wavelengths between 400nm (nanometers) and 700nm (nanometers), which means that it can be seen by humans with optical devices like binoculars or telescopes but not with your naked eye. Visible light also includes colors such as reds, oranges and yellows that are caused by different wavelengths of light
