What Is The Difference Between UVA, UVB, And UVC?

Table of Contents

UVA, UVB, and UVC are terms that can seem very confusing at times. All three rays belong to the sun’s ultraviolet radiations.

What Is UV?

UV is an electromagnetic wave with a wavelength between 10nm and 400nUV is an electromagnetic wave that has a wavelength between 10nm and 400nm. It is shorter than the visible light but longer than X-rays.  This ultraviolet radiation is less than 200 nanometers. It is strongly absorbed by the air. That is why it is called vacuum ultraviolet.

Difference Between UVA, UVB, And UVC In Different Wavelengths

Here are the wavelengths of all three measure in nm:

  • UVA: 420-320nm
  • UVB: 320-280nm
  • UVC: 100-280nm (Ultraviolet rays can be used for sterilization)

Harm to the skin

The effect of ultraviolet rays on the skin is quite bad. Prolonged exposure to UV can damage the skin. Since UVA, UVB, and UVC have varying wavelengths, their impact on the skin is also different.

The shorter the ultraviolet wavelength, the grSo, the shorter wavelength, the greater the radiation hazard.

However, the shorter the wavelength of ultraviolet light, the shorter the wavelength of ultraviolet light, the lesser the radiation penetration in the skin.

Which UV Radiation Is Most Dangerous?

Radiation hazards and penetrability are very dangerous. There is no concrete way to judge the effect of different wavelengths on the skin.

To understand it better, let’s analyze UVA, UVB, and UVC one by one.

1.UVA (320-400nm)

The wavelength of UVA is between 320-400nm. Thus, its wavelength is the longest.

So, we can say that the penetrability of UVA is strong and can easily pass through the atmosphere. After irradiation, it will enter the skin directly. Thus, causing skin diseases.

It should be noted here that UVA can penetrate glass. We recommended wearing sunscreen equipment for protection against UVA. It will reduce the damage to the skin.

2.UVB (320-280nm)

UVB has a wavelength ranging between 280-320nm. A tiny part of UVB can pass through the atmosphere to reach the surface of the earth.

These rays can reach the surface of the skin but can’t enter the inner layer. Scientific research says, UVB can also cause skin diseases. Thus making it harmful for you.

3.UVC (100-280nm)

The wavelength of UVC is between 100-280nm, making it the shortest wavelength of all.

Almost all UVC can penetrate the atmosphere and reach the surface of the earth. UVC can’t penetrate directly to the skin, even if it’s intense ultraviolet light. Additionally, all the existing UVC are made from artificial light sources.

We at Darkness LED Lighting have realized that germicidal lamps (part of) products don’t cause damage to the skin.

Use of UVA, UVB, And UVC In Lamps

With that bit explained, let’s explore the use of UVA, UVB, and UVC in lamps.

UVA use in luminaries:

  • It conforms to the photo-taxis response curve of insects. And can be used to make insect-inducting lamps and mosquito lamps.
  • It is the central area of plant luminosity and can stimulate cyanide for plant lamps.
  • It can identify the fluorescent agent. It makes it glow under radiation and is used in gem identification.
  • When it shines on the scorpion shell, it makes it glow. This attribute makes it worthwhile to be used as a scorpion lamp.
  • It can stimulate the photocatalyst. And can produce vital oxidizing substances that play a part in sterilization and deodorization.
  • You can identify beige and beige fabrics underexposure.
  • The specific wavelength can use absorbed by the photo-initiator in the UV glue. Thus, making a chemical reaction that ultimately promotes curing the UV glue within seconds. It makes it useful for UV curing lamps and nail lamps.

UVB Use In Luminaries:

  • UVB ultraviolet rays have erythema effects on the human body. It can promote mineral metabolism and vitamin D formation in the body. Thus, making it useful for skin detection and treatment of skin diseases that belong to pure physical therapy.
  • UVB can also identify and detect unique materials. These include nucleotides, proteins, fluorescent drugs, food additives, and fluorescent coatings.

UVC Use In Luminaries:

  • UVC can destroy the structure of DNA in bacteria causing them to die directly. It also stops DNA replication and reproduction of offspring needed for sterilization. That is why it is used in various scenarios, such as air purification and sterilization.
