UV Rays or Ultraviolet Rays are ‘ultraviolet rays’ which are harmful rays emanating from the sun. These rays cannot be seen with the naked eye, although you can see or feel them through sunlight or extreme heat. The side effects of these ultraviolet rays are known only after you come in contact with it. If you also want to know what is Ultraviolet. So stay with us in this post till the end.
Ultraviolet rays are a part of the rays emanating from the sun. These rays can also cause severe damage to the skin, which can also take the form of a disease or even cause cancer. These rays show their maximum effect in the summer season. Therefore, the effect of these rays can be avoided only by taking care. But for this first you should know that what is UV Rays, whose information you will get from this article.
What is ultraviolet-
These are the rays emanating from the sun, which are called ultraviolet rays. If the level of these ultraviolet rays becomes high, then it can also cause many kinds of harm to us. We can neither see nor feel these rays. Ultraviolet rays cannot penetrate deep into the body. For this reason, the damage of these rays can be done only on our skin.
Ultraviolet protection means that the ultraviolet rays emanating from the sun, which is called ultraviolet radiation, the thing we use to protect against it is called ultraviolet protection.
Who discovered ultraviolet rays-
Do you know who discovered ultraviolet rays? Ultraviolet rays were discovered by the German scientist ‘Johann Wilhelm Ritter’ in 1801. He found that silver chloride turns black when it is exposed to sunlight. Johann Wilhelm made an observation in 1801, showing that silver chloride (above) darkens wet paper in contrast to violet light. To emphasize the chemical reactions, Johann Wilhelm named these rays as de-oxidizing rays.
Types Of Ultraviolet Rays-
There are also some main types of ultraviolet rays, which are mainly of three types.
1.UVA Rays-
This type of ultraviolet rays damages the skin for a long time. UVA rays destroy the age of the skin cells and are harmful to the DNA of the skin. UVA rays can also cause skin cancer. These rays can cause the problem of wrinkles on the skin.
2.UVB Rays-
UVB rays contain more solar energy than UVA rays. Due to which UVB rays directly damage the skin cells and DNA. UVB rays can cause many skin cancers. UVB rays are responsible for sunburn. The only cure is to avoid these rays.
3.UVC Rays-
These ultraviolet rays have more energy than other ultraviolet rays. UVC rays do not occur in sunlight and the atmosphere and UVC rays do not cause the problem of skin cancer.
| Name | Abbreviation | Wavelength (nm) |
Photon energy (eV, aJ) |
Notes/alternative names |
| Ultraviolet A | UV‑A | 315–400 | 3.10–3.94,0.497–0.631 | Long-wave UV, black light, not absorbed by the ozone layer: soft UV. |
| Ultraviolet B | UV‑B | 280–315 | 3.94–4.43,0.631–0.710 | Medium-wave UV, mostly absorbed by the ozone layer: intermediate UV; Dorno radiation. |
| Ultraviolet C | UV‑C | 100–280 | 4.43–12.4,0.710–1.987 | Short-wave UV, germicidal UV, ionizing radiation at shorter wavelengths, completely absorbed by the ozone layer and atmosphere: hard UV. |
UV Rays Uses-
Along with the disadvantages of ultraviolet rays, there are also some uses. It is useful for us in some way or the other.
Clean Air: Ultraviolet rays help in cleaning the air.
Vitamin D: Vitamin D can be absorbed through these rays. Which is useful in making bones strong.
Special research: It is used by scientists for a specific type of discovery.
Skin diseases: These rays are also used in many types of skin related diseases.
Destroy bacteria: These rays also destroy bacteria.

Advantages of UV Rays-
The effect of ultraviolet rays does not only cause harm, but it can also have many benefits for you, which have been told to you further. Know about the benefits of ultraviolet rays.
It is a source of Vitamin D. The body needs ultraviolet rays from the sun to get vitamin D. It strengthens bones and muscles and increases immunity.
Ultraviolet rays kill germs and prevent infection. It also destroys the microscopic germs from which bacteria or viruses spread.
These rays are also used in the treatment of some diseases related to the skin. Those small animals are able to see fruits, flowers and seeds only through ultraviolet rays.
Apart from this, the animals or kites that fly in the air are able to detect the direction only through ultraviolet rays.
Disadvantages of UV Rays-
Along with the advantages and uses of ultraviolet rays, they also have some disadvantages. These rays are not only beneficial, but there are also some disadvantages of these rays. Let’s know about its disadvantages
Wrinkles on the skin-
Ultraviolet rays can cause wrinkles on your skin. If you are exposed to these rays for a long time, then it is the cause of wrinkles. To avoid this damage, you have to avoid being in the sun’s rays for a long time.
Harmful to eyes-
These rays also harm the eyes. Due to which the eyes start burning and the problem of cataract can also occur. The eyesight starts decreasing. To avoid this, special care should be taken of the eyes.
The ozone layer, which is located at an altitude of about 15 to 25 kilometers above the earth’s surface, provides protection from ultraviolet rays. The ozone layer absorbs the ultraviolet rays coming from the sun, but due to pollution, it has started deteriorating, due to which it started reaching the earth, which is becoming a matter of great concern.
