UV-B and UV-C are filtered by the ozone layer present in the atmosphere and only UV-A reaches to the earth which cause the various skin infection. if we talk about the frequency of the UV-B and UV-C the because of the higher frequency the UV-C is more harmful. UV with the wavelength of 253.7 nm is used for its germicidal activity.

What are Properties of ultraviolet rays?
Ultraviolet (UV) rays have a shorter wavelength and are invisible to the human eye. They can cause skin damage, including sunburn and aging, and can also increase the risk of skin cancer. UV rays are classified into three types: UVA, UVB, and UVC, with UVA being the least harmful and UVC being the most harmful.
What are 3 types of ultra violet radiation?
The three types of ultraviolet radiation are UVA, UVB, and UVC. UVA has the longest wavelength and is associated with skin aging. UVB has a medium wavelength and is responsible for sunburn and skin cancer. UVC has the shortest wavelength and is mostly absorbed by the ozone layer in the atmosphere.
What are the different types of UV light and how do they differ in terms of their effects on human health and the environment?
There are three main types of UV light: UVA, UVB, and UVC. UVA and UVB are the most common types that reach the Earth's surface, with UVA being less harmful than UVB. UVB is responsible for sunburns and skin cancer, while UVA can cause skin aging and eye damage. UVC is the most harmful type but is mostly absorbed by the Earth's atmosphere and does not reach the surface. Overall, UV light can have negative effects on human health, such as skin damage and eye problems, and can also harm the environment by damaging ecosystems and contributing to climate change.
How many altraviolet rays are there?
There are three types of ultraviolet (UV) rays: UVA, UVB, and UVC. UVA rays have the longest wavelength, UVB rays have a medium wavelength, and UVC rays have the shortest wavelength. UVC rays are mostly absorbed by the Earth's atmosphere and do not reach the surface.
Can you get tan with UV 3?
UV 3 does not exist. UV radiation is categorized into three types: UVA, UVB, and UVC. UVA and UVB can cause tanning and sunburn, while UVC is mostly absorbed by the Earth's atmosphere.
Is uv radiation harmful?
UV radiation is very harmful in many ways, first off they are invisible rays that come from the sun, UV radiation is made of ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC). These rays burn skin and cause cancer. UVB and UVC penetrate the ozone layer. UVA and UVB cause skin cancer, for this reason, sunscreens are recommended that block UVA and UVB.

What blocks most ultraviolet radiation from entering earths serface?
The ozone layer in Earth's stratosphere mostly blocks ultraviolet radiation from entering the surface. It absorbs the majority of harmful UVB and UVC radiation, allowing only UVA and some UVB radiation to reach the surface.

How many ultraviolet rays are there?
There are three main types of ultraviolet (UV) rays: UVA, UVB, and UVC. UVA and UVB are the ones that reach the Earth's surface, while UVC is mostly absorbed by the Earth's atmosphere.
How many types of ultraviolet rays are there?
There are three main types of ultraviolet rays: UVA, UVB, and UVC. UVA rays penetrate deep into the skin and are the most commonly encountered in sunlight, UVB rays cause sunburn and are partially absorbed by the ozone layer, and UVC rays are absorbed by the Earth's atmosphere and do not typically reach the surface.
What is the definition of the word UVC?
There are two definitions for UVC. One being radiation in the ultraviolet spectrum and is more hazardous than UVB. The second is medical which has essentially the same meaning.
What is the most harmful type of UV rays?
UVC rays are the most harmful type of UV rays, but they are mostly absorbed by the Earth's atmosphere and typically do not reach the surface. UVB rays are the next most harmful, as they can cause sunburn and increase the risk of skin cancer. UVB rays can also damage the DNA in skin cells.
What molecule acts as a shield to ultraviolet radiation from the sun is?
Molecules act as a shield to ultraviolet rays. These molecules are ozone.
