UV radiation levels above 3 are typically seen during midday hours when the sun is at its peak intensity. This can vary based on location and time of year, but it's generally a good idea to be cautious between 10 am and 4 pm when UV levels are usually higher. You can check local forecasts or use a UV index app to monitor levels in your specific area.

Ozone in the stratosphere above earth consits of?
Ozone in the stratosphere above Earth consists of a molecule made up of three oxygen atoms (O3). It forms a protective layer that absorbs and scatters incoming ultraviolet (UV) radiation from the sun, helping to shield the Earth's surface from harmful UV rays.
How is the ozone harmful?
Electromagnetic waves called UV radiation. Ozone layer blocks out most UV radiation by absorbing it and that is important, because UV radiation can cause skin cancer. To prevent that you also shoud use sunscreen and sunglasses. Use this website and register you can learn a lot about stuff related to these things - jason.org
Which gas present in earth atmosphere can absorb sun ultraviolet radiation?
The gas in Earths atmosphere that absorbs UV radiation is Ozone in an area of the stratosphere called the ozone layer, 10-50km up. Containing 3 Oxygen atoms compared to molecular (diatomic) oxygen that we breath with 2 oxygen molecules.
Are microwaves electromagnetic or machanical?
Microwave is electromagnetic radiation. It's just radio at frequencies above 3 GHz.
At what uv do you need protection?
It is important to protect your skin from UV radiation when the UV index is 3 or higher. This typically occurs between 10am and 4pm when the sun's rays are strongest. It is recommended to use sunscreen, wear protective clothing, and seek shade during these times to prevent sunburn and skin damage.
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.

What are 3 examples of radiation?
X-rays: Electromagnetic radiation with high energy used in medical diagnostics. Gamma rays: High-energy electromagnetic radiation emitted from atomic nuclei. UV radiation: Ultraviolet radiation from the Sun that can cause sunburn and skin damage.
Difference between ultravioletradiation and infrared radiation?
1.In terms of frequency : UV rays = 1 x 1016 to 8 x 1014 Hertz IR rays = 4 x 1014 to 1 x 1013 Hertz 2.In terms of wavelength : UV rays = 3 x 10-8 to 4 x 10-7 meters IR rays =8 x 10-7 to 3x 10-5 meters 3.Source UV rays = excitation of atoms, spark. IR rays = Excitation of atoms and molecules,etc....
3 thing's that destroy ozone?
UV-B or more energetic radiation from the Suncatalysts like water vapor and chlorine- or bromine-containing moleculestime
What are the 3 types of radiation with short wavelength and high frequency?
The three types of radiation with short wavelength and high frequency are X-rays, gamma rays, and ultraviolet (UV) radiation. These forms of radiation have energetic photons and can have harmful effects on living organisms if exposure is not controlled.

What is radiation ultraviolet?
Ultraviolet radiation is the portion of the electromagnetic spectrum extending from the violet end of visible light to the X-ray region. Ultraviolet (UV) radiation lies between wavelengths of about 400 nanometres and 10 nanometres, corresponding to frequencies of 7.5 × 1014 Hz to 3 × 1016 Hz. Most UV rays from the Sun are absorbed by the Earth's ozone layer. UV has low penetrating power, so its effects on humans are limited to the skin. These effects include stimulation of production of vitamin D, sunburn, suntan, aging signs, and carcinogenic changes. UV radiation is also used to treat jaundice in newborns, to sterilize equipment, and to produce artificial light.
What is the frequency of ultra-violet?
The wavelength of ultraviolet light is between 10 and 400 nanometers (nm).From the wavelength you can determine the frequency. If you divide the speed of light by the wavelength, you can calculate the frequency.The frequency range would be from 7.5 x 1014 Hz to 3 x 1016 Hz.
Are microwaves electromagnetic or machanical?
Microwave is electromagnetic radiation. It's just radio at frequencies above 3 GHz.
Why is the risk of sunburn greatest from 11AM to 3PM?
The risk of sunburn is greatest from 11 AM to 3 PM because this period coincides with the sun's highest position in the sky, resulting in the most intense ultraviolet (UV) radiation. During these hours, the UV rays have a shorter path through the atmosphere, leading to increased exposure on the skin. Additionally, factors such as reflection from surfaces like water, sand, and concrete can further amplify UV radiation during this time, heightening the risk of sunburn.
