What is Ultraviolet Light?
UV rays (Ultraviolet radiation) are a type of radiations that are electromagnetic. These
come from either sun or from other resources that are made by man. These other
resources are like welding torches and tanning beds. Any form of source which sends out
any kind of energy or emits any kind of rays is called radiation. There are tons of
radiations that vary from one another based on their different radiation levels. There are
radiations that are very high in frequency like gamma rays and x-rays. In addition to this,
there are radiations that are low in frequency like radio waves. However, when it comes to
ultraviolet rays, they are considered to fall in the middle of these frequencies and
spectrum. Their energy is more than lights that are visible but they are not as high in
frequency as x-rays.
When it comes to ultraviolet radiations, they also differ from one another. Thus, there are
many types of Radiations. These are typically based on the energy which they emit.
Radiations that are ionized in nature are typically considered to be the Rays that are very
high in energy. Why are these considered ionized radiations? It is because their energy
level is so high that they have the power to remove or break an electron. It can be broken
from either a molecule or an atom. This process is called ionization. However, if these
radiations are used on the body then they are said to have a very damaging impact on the
cell of DNA. Yet, these Radiations that are very high in energy are not so high that they
can easily penetrate in the body. Rather, they can only affect the skin area. But, there are
genetic cells everywhere in the body which means that if these rays have a dangerous
impact on skin then these must be avoided at any cost. It is also studied that if these are
used on skin, they can turn the normal cells into cancerous cells.
Types of UV rays
Ultraviolet radiations are divided into three major groups. These groups are as
