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 is ultraviolet radiation where does it come from what is uv index and how is the uv index determine?
Ultraviolet (UV) radiation is a type of electromagnetic radiation that comes from the sun and can also be produced by artificial sources like tanning beds and some lamps. The UV index measures the level of UV radiation from the sun at a particular place and time, which helps to inform people about the potential risk of harm from sun exposure. The UV index is determined based on factors like the angle of the sun, cloud cover, and ozone levels in the atmosphere.
What is a harmful effect of UV radiation of people?
There are harmful effects of UV on people. People can suffer lifelong from fatal problems.
Does earth's atmosphere block all uv radiation from space?
No, Earth's atmosphere does not block all UV radiation from space. It does absorb a portion of the UV radiation, particularly the most harmful UV-C rays. However, UV-A and UV-B rays are able to penetrate the atmosphere to some extent and reach the Earth's surface.
Which are more energetic photons of UV-A radiation or photons of UV-B radiation?
Photons of UV-B radiation are more energetic than photons of UV-A radiation. UV-B radiation has shorter wavelengths and higher energy levels compared to UV-A radiation. UV-B radiation is classified as potentially harmful to human health, while UV-A radiation is less energetic and is more commonly associated with tanning and aging effects on the skin.
Why is the ozone layer important to all living things?
Ozone layer reflect UV radiation. UV radiation is very harmful
What layer of the atmosphere is harmful UV radiation absorbed?
Harmful UV radiation is mainly absorbed by the ozone layer, which is located in the stratosphere of the atmosphere. The ozone layer helps protect Earth by absorbing most of the sun's harmful UV radiation before it reaches the surface.
How does the ozone filter out harmful radiation from the sun?
Ozone molecules in the Earth's stratosphere absorb and scatter incoming ultraviolet (UV) radiation from the Sun, preventing the harmful UV-B and UV-C rays from reaching the Earth's surface. This absorption process converts the UV energy into heat, thereby protecting life on Earth from the damaging effects of excessive UV radiation, such as skin cancer and cataracts.
Are all types of skin damaged by harmful UV radiation?
Yes.
Which gases absorb ultraviolent radiation?
Ozone (O3) in the stratosphere absorbs ultraviolet (UV) radiation, particularly UV-B and UV-C. This absorption plays a crucial role in protecting Earth's surface from harmful UV radiation. Additionally, certain greenhouse gases like methane and nitrous oxide can also absorb some UV radiation in the upper atmosphere.
What does ultraviolet radiation from the sun do to the skin and cells?
UV radiation is harmful to skin. It causes skin cancer.
How does uv and radiation relate?
UV (Ultraviolet) radiation is a type of electromagnetic radiation produced by the sun. It is known for causing sunburn and skin damage. UV radiation can be harmful to living organisms, including humans, if overexposure occurs.
Which part of atmosphere screensout the harmful radiation from the sun?
The ozone layer, located in the stratosphere, screens out harmful ultraviolet (UV) radiation from the sun. This layer absorbs and filters out much of the UV radiation before it reaches the Earth's surface, protecting living organisms from its harmful effects.
