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. For more information about the EM spectrum, please visit https://en.wikipedia.org/wiki/Electromagnetic_spectrum

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. Link for more information about the difference
between UV lights. Genix Lite and Car Genix are products made by IADIY. 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
