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.
Would it make sense to place an x-rays or gamma ray telescope on a mountaintop?
No because, most ultraviolet radiation are blocked by earth's atmosphere.
Does a star's spectrum show all of its elements?
The spectrum shows:the "blackbody radiation - a continuous spectrum that is related to the temperature of the surface of the starlines that are related to levels of energy that electrons jump, releasing photons, and"dark" lines which show energy levels of electrons belonging to elements in the atmosphere or the intervening space which block some radiation
Why do greenhouse gases warm the atmosphere but other gases do not?
Greenhouse gases don't "warm the atmosphere". What they do is trap heat.Why is because that's the definition of "greenhouse gas". Okay, a little more detail: they're transparent to high frequency radiation (visible light and UV) but largely opaque to lower frequency radiation (like IR). So energy in the form of visible light gets to the surface just fine, but when it's time to reradiate it as heat, greenhouse gases block the emission of the lower frequency IR "heat" radiation.
What element is used to block out dangerous radiation?
Alpha Radiation ( α ) – Least penetration. Will be blocked by a single sheet of paper. Beta Radiation ( β ) – More penetration than alpha. Blocked by a few mms aluminium. Gamma Radiation ( µ ) – Strong penetration. Needs a least a few inches of lead to block.
Which gas can block UV radiation in the upper atmosphere?
The upper atmosphere is also known as the stratosphere. The gas that can block ultra-violet radiation in the stratosphere (a.k.a. upper atmosphere) is ozone.
Why do some telescopes that collect electromagnetic radiation in the shorter wavelengths such as ultraviolet or gamma rays need to be placed either in dry areas or outside the atmosphere?
The atmosphere tends to block many of those frequencies. (It's not so much dry, it's as high as possible.)
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.
What materials can block electromagnetic radiation?
That depends on the wavelength of the radiation.chicken wire can block radiation with a wavelength longer than about 10cm.a metal screen with 2mm holes can block radiation up to microwaves.most solids can block IR and visible light.lead is typically needed to block x-rays.many meters of lead and/or concrete is needed to block gamma rays.
Why can infrared telescopes operate from high flying aircraft and high mountain tops whereas Xray telescopes must be place in orbit?
Current telescopes detect different wavelengths of "light," which, in general, is called electromagnetic radiation. Earth's atmosphere is transparent to infrared radiation - it can easily transmit though our atmosphere. Therefore we can easily detect it from within Earth's atmosphere. However, X-Rays do not easily transmit through the Earth's atmosphere, so we must place our X-Ray detectors OUTSIDE of our atmosphere, ie. in orbit around the earth.
What does the fusion of hydrogen in stars release?
Heat, light, and a mixture of all other kinds of radiation, both ionizing and electromagnetic, as a result of the fusion reaction. Much of it is harmful to life on Earth but the Earth's atmosphere and ozone layers block most of it from coming through to the surface.
What to layers of the atmosphere protect us?
Fine, I'll answer your homework question. The layers in the atmosphere block solar radiation, debris such as meteors from space, and allow the force of gravity to exist.
What is one purpose that the atmosphere serves?
The atmosphere serves to block many harmful waves radiating from outer space. It also traps some infrared radiation which warms the earth.
What elememt is used for radiation shields?
Lead is usually used because of its density and ability to block electromagnetic radiation.
Does a planet need atmosphere to have a Greenhouse Effect?
Yes. The greenhouse effect is caused by gasses that block thermal radiation from a planet's surface.
What is the layer of atmosphere that helps block the uyltraviolet radiation rays?
Ozone layer protects us from UV rays. It is present as the ozone layer.
Is electromagnetic radiation the only way to examine the deep reaches of space right now?
You don't even have to go to "... the deep reaches of space". Electromagnetic radiation is also the only way to communicate with the International Space Station right now, roughly 400 km (250 miles) up. In fact, now that I think of it, electromagnetic radiation is the only way to communicate in real time with a person living on the next block, except perhaps for smoke signaling.
