What is Ultraviolet Light?thetravelbrief.com/tips/atlanta-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 follows;

1. UVA Rays –these are the type of rays which have the lowest form of energy when it

comes to UV rays. Their impact can be understood by the simple fact that if they get in

contact with the skin then there rays can make the cells of the skin to age quickly.

Moreover, these rays can also cause damage to the skin indirectly as they can damage the

DNA of skin cells. The main link between Rays and skin is that it causes long term damage

like wrinkles and development of cancer cells.

2. UVB Rays –these rays a little bit more energy as compared to UVA rays. These rays

have the power to affects the cells of skin much more directly. It is the impact of these

rays that sunburn happens on the skin. These rays are the ones which mostly causes

cancer.

3. UVC Rays –these rays have the highest level of energy. However, due to high energy

levels these rays mostly stay higher than the base of earth. These interact openly with

ozone layer. This explains how high it stays in the air. Thus, these rays are generally not

able to reach to the ground that is why they are not risky to human bodies. On the other

hand, these rays are also emitted from various sources that are made by man like mercury

lamps, bulbs that are UV sanitized, and welding torches etc. These rays are also used in

creating germs and bacteria killing devices.

Sunlight –the main source of UV light

Sunlight is considered to be the biggest and the main source through which we receive UV

light or UV radiations. Even though as per the researches, it is said that these rays are

considered to be a very minor part of the whole portion of rays of sun. This is the basic

reason why the amount of rays which reaches the ground from sun also differs greatly. It

is also mentioned in various studies that the 95 percent of the UV radiations which reach

to the ground are mostly UVA rays, and the remaining are UVB rays which are almost 5

percent in ratio. These rays also vary in strength because of various factors like which

time of the day it is that these rays are reaching to the ground. In addition to this, sunlight

also vary from season to season. Moreover, the distance which the place has from the

equator or the latitude also counts when it comes to Radiations. Moreover, on higher

altitudes Radiations that reach to the ground are higher in strength. Moving forward, if

the weather is cloudy than the strength of UV light also vary a bit. Lastly, these have the

tendency to bounce off from the surfaces like sand, water, pavement, grass or even snow.

Therefore, making the exposure of them further stronger.
