Why and how does our atmosphere protect us from the electromagnetic spectrum?
Wiki User
∙ 8y ago
- the thickness of the atmosphere attenuates gamma rays to safe levels at the surface
- the thickness of the atmosphere attenuates x-rays to safe levels at the surface
- ozone in the top layer of the stratosphere absorbs most ultraviolet
- the atmosphere does not significantly absorb or attenuate visible light
- water vapor in the atmosphere absorbs most infrared
- water vapor in the atmosphere attenuates microwaves
- the atmosphere does not significantly absorb or attenuate radio waves of longer wavelength than microwaves

How do the layers of the earth work together?
The various layers of atmosphere protect us. They protect us from the UV rays, Control the temperature etc.
What kind of electromagnetic wave does a CD player?
Digital Versatile Disc (DVD) uses 650nm wavelength laser diode light (part of the electromagnetic spectrum, in visable light section) which allows us to see it. CD uses 780nm wavelength, just outside of the electromagnetic spectrum, hence why we cannot 'see' it, only hear.
Why does the continuous electromagnetic spectrum have a sharp limit on the short wavelength end?
There is a simple explanation for the sharp limit on the short wavelength end of the electromagnetic spectrum. The shortest electromagnetic waves are generated by the reactions of subatomic particles. At some point, it just isn't possible to generate a higher frequency electromagnetic wave. We can imagine them, but they cannot be "made" by us (in particle accelerators) nor are they "caused to occur" in nature (by catastrophic cosmic events).
What does earths atmosphere protect from us?
The ozone layer protect us from the UV raysSo we don't burn up from the Sun's ultra-violet rays.
How does the atmosphere protect us from sunburn?
It protects us by the ozone layer filtering most of the ultraviolet rays.
When you stand in the sun which part of the electromagnetic spectrum is NOT striking you?
All wavelengths shorter than the low part of the ultra-violet spectrum are shielded from us by the atmosphere.
How is the electromagnetic spectrum useful?
Visible light, which lets humans and other animals see, is part of the electromagnetic spectrum. RF (radio frequency) waves are part of the electromagnetic spectrum. RF transmissions carry radio and television broadcasts. They have the lowest frequency. Microwaves are part of the electromagnetic spectrum. X-Rays are part of the electromagnetic spectrum and have the highest frequency..
What two features of earth protect us from the sun's radiation?
strong magnetic field deflects charged particle radiation around the earthozone layer absorbs much of the ultraviolet electromagnetic radiation as it enters the atmosphere
Does the atmosphere protect us from meteorites?
YES
Does the earth atmosphere protect us from zero gravity?
No
Which part of the electromagnetic spectrum generally gives us your best views of stars forming in dusty clouds?
Infrared
How does your atmosphere protect us?
Our atmosphere also reflects UV and makes meteors burn up.
What does theozone layer protects use from?
The ozone layer protects us from UV's. UV's are a part of sun's electromagnetic spectrum.
Are microwaves good or bad for us?
As with any other wavelength of the electromagnetic spectrum, they can be good or bad depending on the use to which they are put.
Is the electromagnetic spectrum harmful?
Certain parts of it can be. High frequency waves such as X-rays, gamma rays, and ultraviolet light can cause radiation burns and cancer. At the same time, life could not exist without the electromagnetic spectrum. The sun heats the earth through electromagnetic waves, and the light that drives photosynthesis is also part of that spectrum. Visible light, which allows us to see, is in the same range.
How do the layers of the earth work?
The various layers of atmosphere protect us. They protect us from the UV rays, Control the temperature etc.
How do we know there are types of electromagnetic radiation other than visible light?
Because experiments and technology have enabled us to prove the electromagnetic spectrum extends beyond the narrow band of visible light.
