For IR, visible, and UV radiation; any shiny surface will do. For acoustic radiation, any massive smooth surface will do. For em radiation, any material with a very different dielectric constant from that of air will do. For ionizing radiation, there is a lot of money to be made from this discovery. That problem is yet (mainly) to be solved.
What else can I help you with?
Why is much of the sun's radiation reflected back in to space by earth?
Such reflection is called the albedo. For the earth it is 30 - 35%
How is gamma radiation used in medicine?
gamma radiation is used in cancer treatment. the most common source of gamma radiation is.
Is sunlight just like radiation?
Yes sunlight is composed of ultraviolet rays which are electromagnetic radiation
Does a pet scan use radiation?
Doesn't it make you wonder why these radiation questions have not been answered??
How long does radiation stay in your body after a cat scan?
Radiation from a CT scan typically does not remain in your body; it is absorbed and quickly dissipated. The radiation exposure from a CT scan is instantaneous, and the effects are not cumulative. However, the dose of radiation can vary depending on the type of scan and the area being imaged. Overall, the amount of radiation used in a CT scan is considered safe and is monitored to minimize risks.
How is the sun reflecting it radiation into space?
The sun does not reflect its radiation into space.
Does ozone reflect or absorb UV radiation?
Ozone absorbs UV radiation.
What sort of radiation absorbs or reflect radiation?
It doesn't absorb clever. It penetrates, and it can penetrate paper, smoke, a layer of skin and thin aluminium.
Do mirrors reflect without light?
Mirrors reflect whether there is anything to reflect at the minute. Beside light they can also reflect heat radiation.
How might a thick puffy cloud reflect a different amount of the Sun's radiation than a thin wispy one?
Thick puffy cloud reflects suns radiation thick clouds reflect radiation keeping earth cool. Thin wispy cloud reflects sun radiation thin don't reflect as much radiation allowing the earth to warm.
What the fraction of radiation a surface can reflect is called?
Reflection
Does the ozone layer reflect or absorb UV radiation?
The ozone layer absorbs UV radiation.
What does radiation bounce off of?
Radiation can bounce off surfaces such as metal, mirrors, and other reflective materials. The ability of a material to reflect radiation depends on its composition and surface finish. Smooth and polished surfaces tend to reflect radiation more effectively than rough or absorbent surfaces.
Do clouds reflect sun's radiation?
Yes, clouds can reflect incoming solar radiation due to their high albedo, which is the measure of how much sunlight is reflected off a surface. This reflection can have a cooling effect on the Earth's surface by reducing the amount of solar radiation that reaches it.
How do clouds reflect heat to earth?
Cloud cover prevents IR radiation and light from escaping to space, preventing cooling by radiation.
How does color affect radiation and absourbtion?
Color affects radiation and absorption through reflection and absorption of different wavelengths of light. Darker colors tend to absorb more radiation and heat up more quickly, while lighter colors reflect more radiation and stay cooler. This can impact a material's ability to absorb or reflect solar radiation, affecting its temperature and energy efficiency.
Why is aluminum used to make fireman clothes?
Aluminium reflect infrared radiation.
