What is Electromagnetic Spectrum?

Electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies. Electromagnetic waves also known as EM waves, are produced by vibration-charged particles and have electrical and magnetical properties. Photons travel in a wave-like pattern at the speed of light. The EM spectrum is divided into 7 categories. Each category represents how energetic the photons are, and the size of the wavelength; Gamma rays, X-rays, UV rays, Visible lights (rays), Infrared (IR) waves, microwave waves, and Radio waves. The lower the energy, the longer the wavelength is. Gamma rays have the shortest wavelength and the highest energy, while Radio waves have the lowest energy and longest wavelength.

            Each category has its own characteristics, such as how they interact with matter, how they are produced, and how the applications for each wavelength. For example, microwave and radio waves have a very broad range of applications. The uses include microwaves, cell phones, and radar, etc. 

            Infrared rays are the heat that we feel from the sun or other heat sources. Followed by the visible light, which is the color we see around us. It is a type of wavelength that is reflected by the sun or light. The visible wavelength for the human eye is from 400nm to 700nm. The short wavelength limit in the vicinity of the Planck length. 

            UV rays, X-rays, and Gamma rays have ionizing factors therefore, their photons have the energy to ionize atoms and cause chemical reactions. For example, when UV light contacts our skin, we produce        Vitamin D. However, overexposure to UV light can cause damage to our skin because UV rays are ionizing factors.

It utilizes UVC rays and photocatalysts to react to organic particles in the atmosphere. X-Rays are normally used in hospitals; as X-Rays can pass softer tissues but not dense materials such as our bones. It is also used in airports for baggage checks. 

Electromagnetic Pollution

            Electricity is the movement of electric charges, this movement produces an eclectic field and magnetic field. This is called electromagnetic radiation(EMR). Different parts of the electromagnetic spectrum correspond to different types of radiation. More than half of them are harmless to humans. But the shorter the wavelength is, the more harmful it is to the human body. This is due to the energy of short wavelengths having the ability to rip electrons out of their atoms, which makes the atom very active and causes genetic damage. 

             We are constantly surrounded by natural and harmless sources of electromagnetic radiation such as the sun, earth, moon, clouds, etc. Ever since the industrial revolution, we have significantly expanded our media environment. Many scientists have done a lot of research about electromagnetic pollution. For more information about radiation, please visit
