How does earth's atmosphere filter some of the electromagnetic radiation?

It scatters white light (blue sky) and filters out some ultra-violet, infra-red, x-ray, and gamma ray wavelengths.

What does clouds protect us from?
Clouds are not a form of protection. They dim the sunlight we receive but do not filter UV radiation. They can and do reduce light and infra red radiation reaching the surface of the earth
Can you get a sun burn on the moon?
No, you cannot get a sunburn on the moon. The moon does not have an atmosphere to filter or scatter the sunlight, so the intensity of the sun's ultraviolet (UV) radiation is too weak to cause sunburn. However, prolonged exposure to direct sunlight on the moon can still be harmful to the eyes and skin.
Why is the sunrise orange or white?
At lower altitudes and low sun (dawn/dusk) the sunlight has to shine through more atmosphere. The Sun emits electromagnetic radiation, of which white light is a part. White light can be split into the colours of the rainbow. The Blue end of the spectrum is the shorter wavelength, and the Red end is the longer wavelength. The shorter/longer the wavelength the less/more penetrating they are. e.g. you cannot see light/uv rays (shortwavelength) through a brick wall, but you can feel IR(heat)( longwavelength) through a brick wall. So the longer wavelengths from the Sun (yellow/orange/red) will penetrate further through the atmosphere. Hence you see this colour light with a setting/rising Sun. Contrast this , when the Sun is high in the sky (midday) sunlight has less atmosphere to penetrate through, so it follows that the shorter wavelengths can pass through and the light changes to white. Do not confuse this with 'Blue Sky' that is a different phenomenon.
Why do sunlight has seven colours?
Sunlight has seven colors because the atmosphere acts as a filter, it changes the color, for instance the setting sun, looks yellow or orange.
Why the sun appears to be much redder just before it sets then it is around noon?
Sun's rays are white and a mixture of different frequencies or colours of light. The dust in the atmosphere reflects mostly blue light and light of higher frequencies (which is why earth looks bluish in pictures taken from outer space); and allows the remaining yellows and reds to pass through to the ground. So observers at ground level sees the sun as though looking through a red coloured glass or filter <P>At dawn, and at sun set, the sun's rays have to pass through a longer path through the earths atmosphere, and less blue light reaches the ground. Therefore the sun appears to be redder when viewed from the surface of the earth, just before it sets or at day break
Does Mars receive radiation from the Sun?
Yes. Earth receives radiation. The atmosphere acts as a filter. The atmosphere of Mars is thinner than Earth. Mars receives radiation also.
What layer of the atmosphere absorbs x rays coming from the sun?
The atmosphere does not filter X-rays. It does filter ultraviolet radiation, in the ozone layer.
Why are the sun's rays more dangerous on the moon than on earth?
Because the Moon has no atmosphere to filter out dangerous radiation.
Where is over 95 percent of incoming ultraviolet radiation absorbed?
in the atmosphere;in the Ozone Layer(The ozone molecules filter out the harmful UV rays.)
What is the main type of electromagnetic that makes up the solar radiation that reaches earth?
Well techinichally it is just a radiation that comes from the sun and the readiation is a electromagnetic field
What does an EMI filter do?
EMI stands for electromagnetic interference. An EMI filter prevents unwanted electromagnetic emissions from being detected by a receiver.
Can a radioactive particle filter be suspended in a plume of radioactive smoke or steam to vacuum and reduce radiation released into the environment during a meltdown?
Yes but it can't stop all radiation going in the atmosphere, it slow slows it down.
Does Walmart carry electromagnetic interference filter in Milwaukee, WI?
Walmart does not share its data with electromagnetic interference filter because parameter will differ for both
Why is it cold at the poles?
The answer to this question involves the angle at which solar radiation is intercepted by the earth's atmosphere. The rule is that if solar radiation is incident perpendicular to the atmosphere the solar radiation that is incident on the earth's surface will be greatest. Incoming solar radiation at the poles comes in at a sharper angle and is spread over a greater surface area of atmosphere than at the equator. In this way, the poles have more of an atmospheric filter and experience less radiation per area time and hence have lower average temperatures.
Is sunlight that hits the Earth straight on dimmer or brighter?
Dimmer or brighter than what? Sunlight hitting the earth straight-on, as at the equator, is brighter, hotter and includes more intense ultraviolet radiation. Sunlight at an angle, the poles, for example, is less intense because it has to travel through more atmosphere. The atmosphere acts as a filter, effectively dimming the sun's radiation.
How does the ozone filter out harmful radiation from the sun?
The ozone can filter harmful radiations. These are the UV rays of the sun.
What is the stratosphere function of the earth atmosphere?
its a secondary filter
