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
What is ultraviolent radiation?
Ulraviolet 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.
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.
What are 3 uses for ultraviolet radiation?
When we expose our skin to UVB it stimulates the production of vitamin D, Another way is curing special glues with a UV light to harden the glues quickly. UVC is able to disable the strands of DNA in bacteria and viruses and make them inert.
3 physiological factors that affect skin color?
1.melanin 2.hemoglobin 3.carotene

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 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 are the 5 effects of air pollution?
1. Greenhouse Effect 2. particulate contamination 3. increased UV radiation 4. acid rain 5. increased ozone concentration
What are the properties of nuclear radiation?
wheat are the common properties and characteristic of light

What does a uv rating of 3 moderate mean?
A UV Index reading of 3 to 5 means moderate risk of harm from unprotected sun exposure. * Take precautions, such as covering up, if you will be outside. * Stay in shade near midday when the sun is strongest. Me and My Shadow An easy way to tell how much UV exposure you are getting is to look for your shadow: * If your shadow is taller than you are (in the early morning and late afternoon), your UV exposure is likely to be low. * If your shadow is shorter than you are (around midday), you are being exposed to high levels of UV radiation. Seek shade and protect your skin and eyes.
What is an Example of where energy transfer by radiation is occurring?
Some examples of energy transfer by radiation are: 1) standing in sunlight and feeling the heat on your face (UV radiation is entering the skin, converting to infrared radiation, and is absorbed by your tissues); 2) sitting near a fire and feeling the heat on your skin (infrared radiation transfer); 3) chemical reactions that occur due to a source of radioactivity (gamma radiation, being high-energy photons, travel from the radioactive source through the air into the target sample, and induce chemical reactions
