COMPREHENDING THE ELECTROMAGNETIC SPECTRUM

The electromagnetic spectrum is a description of the range of electromagnetic
waves that range from the visible light to gamma rays. This is a vital part of
science and understanding the electromagnetic spectrum is important. In this
article I am going to discuss some of the most important aspects of this range
and how they function.
Infrared

Infrared is the electromagnetic spectrum of radiation that extends beyond red
portion of the visible spectrum. Infrared spectrum is utilized to measure
thermal properties of objects. It is also utilized in night vision equipment.

Generally, infrared is classified into near infrared and infrared. Near infrared
is the wavelength range that includes the frequencies with the smallest
frequencies. These wavelengths are within the range of 1 to 5 microns. There are
also intermediate and long infrared bands. Each is characterized by their own
distinct wavelengths.

The most well-known application of infrared is for military night vision
goggles. These goggles transform infrared into visible wavelengths for nighttime
vision. However, infrared light can also be used for wired and wireless
communication.

There isn't any evidence to suggest a connection between infrared radiation and
skin cancer. However, the International Commission on Non-Ionizing Radiation
Protection (ICNIRP) has issued guidelines on the limit of exposure to incoherent
visible and infrared radiation.
Visible light

Visible light is a part of the electromagnetic spectrum. The Sun is the main
source of light. The other sources for visible light include the moon and the
stars. It is important to know that we are unable to see ultraviolet and
infrared wavelengths. But, we can see the red and blue light. The two colours
blend in what we call white light.

There are numerous other obscure components of the electromagnetic spectrum,
including infrared and radio waves. Certain of them have been used for
television, radio as well as mobile communication. However, the most effective
way to make use of them is to develop the correct type of filter. In this way we
can lessen the negative consequences of these elements to our bodies. In
addition, we can create an online environment where we can study these
components, even with our eyes off.

Although the longest and shortest wavelengths of the visible light could be the
most noticeable however, the most energy efficient and visually pleasing
wavelengths can be found in the infrared shortwave (SWIR) as well as microwave
frequency.
UV

Ultraviolet (UV) radiation is part of the electromagnetic spectrum. It can be
used for various purposes. However, electromagnetic spectrum meaning is also
dangerous. UVB and UVC radiation are not good for eyesight and can cause skin
disease.


This type of energy is absorbed by molecules and initiate chemical reactions.
The molecule that absorbs it can release visible light and emit fluorescence.

The spectrum of the ultraviolet is divided into three major categories, namely,
the extreme, the near, as well as the middle. Typical ultraviolet sources
include lasers, arc lamps and light-emitting diodes.

While UV rays have wavelengths that are shorter, UV rays are shorter in
comparison to X-rays they have more energy. This is useful for breaking the
bonds between chemical compounds. The waves are often referred to in the form of
radiation that is nonionizing.

In biochemistry, the UV spectrum is typically used to determine the absorption
of a particular substance. There are many types of compounds that exhibit
significant absorption bands of light that are visible in UV.


Ultraviolet light is part of the spectrum known as electromagnetic, and is
created by the sun. Its spectrum is between 10 and 4100 nanometres, and its
frequencies are from 800 THz to 30 PHz. However, most people cannot be able to
see it.
X-rays

The X-rays, also known as electromagnetic radiation, have high energy. Contrary
to gamma and ultraviolet light, X-rays have wavelengths shorter than visible
light, and can penetrate thin objects. They are employed in a variety different
medical procedures, like imaging bone and tissue. Several types of X-rays exist.

Hard X-rays are produced when an electron that is incoming collides with an
atom. This results in a vacancy in the atom's electron shell. A second electron
may fill the vacancy. Alternatively, the incoming electron might kick out an
atom. In this case, some of the energy generated by the photon is transferred to
the scattering electron.

A X-ray should not be mistaken for the X-band, which is a low-energy spectrum
that is part of the electromagnetic spectrum. Although the two bands are
separated by a few hundreds of nanometers each, they do not share the same
features.

Because X-rays are penetrating the body, they can be used in many different
ways. For example, X-rays are utilized in security screening to detect cracks in
baggage. Additionally, they are utilized in radiotherapy for cancer patients.
X-rays are also used to discover the structural components of materials such as
cement.
Gamma rays

Gamma Rays are very high-energy types that emit electromagnetic radiation. In
fact, all extremely high-energy photons are gamma Rays. They are generated
through nuclear decay as well as high-energy physics experiments. They are the
most energetic photons that are found in the electromagnetic spectrum.

Because of their intense energy, gamma radiations are capable of piercing deep
into materials. The possibility exists for gamma beam to penetrate several
inches of lead.

A variety of high-energy physics experiments generate the gamma radiation. For
example the radiation of particles from relativity centered by the magnetic
field of a hypernova can be detected at 10-billion light years.

Gamma rays can be emitted by the nucleus in some radionuclides after they have
gone through the process of radioactive decay. Other sources of gamma rays
include atomic transitions as well as annihilation and sub-atomic particle
interactions.

The majority of gamma radiation in astronomy are derived from other mechanisms.
Gamma rays emitted by supernovae and nuclear fallout are among the most
energetic electromagnetic radiation forms. This makes them a great source for
exploring the universe.

Certain gamma radiations could cause harm to cells within the body. However,
gamma rays aren't as ionizing as beta or alpha rays. Therefore, it is more
unlikely that they cause cancer. Nevertheless, gamma rays can alter the DNA
structure and can cause burns. Even the smallest amount of gamma rays may cause
ionization in the body.
