What are 2 different types of ultraviolet radiation?

What are 2 different types of ultraviolet radiation?

There are two basic types of ultraviolet rays that reach the earth’s surface—UVB and UVA. UVB rays are responsible for producing sunburn. The UVB rays also play the greatest role in causing skin cancers, including the deadly black mole form of skin cancer (malignant melanoma).

What is the difference between UVA UVB and UVC radiation?

UVC is the shortest and not long enough to reach our skin; UVB rays come in contact with the outer layer of the skin; UVA radiation penetrates deeper into the skin, all the way into the inner layers. UVC rays are actually the strongest but are mostly absorbed by the atmospheric ozone.

What do you mean by ultraviolet radiation?

Invisible rays that are part of the energy that comes from the sun. Ultraviolet radiation that reaches the Earth’s surface is made up of two types of rays, called UVA and UVB. Ultraviolet radiation also comes from sun lamps and tanning beds. Also called UV radiation.

How many types of UV light are there?

three
The most common form of UV radiation is sunlight, which produces three main types of UV rays: UVA. UVB. UVC.

Which of the following is a use of ultraviolet radiation?

UV radiation is widely used in industrial processes and in medical and dental practices for a variety of purposes, such as killing bacteria, creating fluorescent effects, curing inks and resins, phototherapy and suntanning.

What does the C stand for in UVC?

ultraviolet
ultraviolet. ultraviolet C (UVC) ultraviolet radiation with wavelengths between 200 and 290 nm; all of this type of radiation is filtered out by the ozone layer so that none reaches the earth’s surface. Ultraviolet C is germicidal and is also used in ultraviolet phototherapy.

What are some examples of ultraviolet light?

Examples of Ultraviolet Waves

• A UV light equipped disinfectant.
• A UV lamp.
• Sterilizing a room with the help of UV rays.
• A UV lamp curing skin diseases.
• UV bed for tan removal.
• UV rays creating northern lights.
• UV liight used for decoration.

Which of the following is use of ultraviolet radiation?

What are the different types of UV radiation?

UV radiation is classified into three primary types: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These groups are based on the measure of their wavelength, which is measured in nanometers (nm= 0.000000001 meters or 1×10-9 meters).

Do clouds block UV?

Most clouds block some degree of UV rays. The thicker and denser the clouds, the more UV rays are filtered. [2] But clouds can also enhance the intensity of the ultraviolet rays that reach ground level.

What are the effects of UV rays?

These effects include mainly sunburn (or erythema) and tanning (or pigment darkening). The chronic effects of UV exposure can be much more serious, even life threatening, and include premature aging of the skin, suppression of the immune system, damage to the eyes, and skin cancer. UV radiation can cause serious negative impacts on cells.

What are the benefits of UV radiation?

The three primary health benefits of UV exposure are the production of vitamin D, improvement in mood, and increased energy. Moderate exposure to UV radiation is a good source of vitamin D. This vitamin aids in the regulation of calcium metabolism, insulin secretion, blood pressure, immunity, and cell propagation.
