Not exact matches

When a unit of electromagnetic radiation such as a microwave hits an electron, it absorbs it and changes position.

Pendry knew he was in uncharted territory, but at first he didn't comprehend the magnitude of his idea: By combining the electrical properties of Marconi's radar - absorbing material with the magnetism imparted by the copper wire, he had unknowingly figured out how to manipulate electromagnetic radiation, including visible light — making wild applications like Harry Potter's invisibility cloak suddenly within reach.

Upon exposing a metallic surface to electromagnetic radiation that is above the threshold frequency or threshold wavelength (which is specific to the type of surface and material), the photons are absorbed and current is produced.

Most types of electromagnetic radiation, except for visible light and radio waves, are absorbed by the Earth's atmosphere.

Dark matter is an unseen substance that does not, as CERN explains, absorb, reflect or emit electromagnetic radiation such as light.

The Sun is important because it provides the Earth heat, it creates our daylight by emiting electromagnetic radiation, it allows plants to grow via photosynthesis which in turn absorb carbon dioxide and create oxygen.

The World Health Organization (WHO) estimates that the typical absorbed dose of mercury from amalgams is one to twenty - two micrograms per day, with most values in the range of one to five micrograms per day.16 Various factors, including gum chewing and bruxism, can increase these exposures to an upper range of about one hundred micrograms per day.7 Preliminary evidence also suggests that certain types of electromagnetic radiation, including EMR from mobile phones and from magnetic resonance imaging (MRI) may increase the release of mercury vapor from dental amalgams.17

If you are designing an atmospheric model with molecules that absorb or emit ir energy, N2 and O2 would not be modeled as absorbing or emitting ir energy through vibrational interactions with electromagnetic radiation.

As I explained earlier here, AGWSF has eliminated all differences of property and process between the wavelengths to deliberately create this confusion between light and heat, in the meme: «all electromagnetic radiation is the same and all create heat on being absorbed».

Contrary to the AGWScienceFiction meme «all electromagnetic radiation is the same and all create heat on being absorbed».

The AGWSF meme for the plebs is that «all electromagnetic radiation is the same» and «all create heat on being absorbed», and it also provides «rebuttal memes» for their apologetics teams, «haven't you heard of conservation of energy?»

Carbon dioxide absorbs solar electromagnetic radiation which makes it warm, That warmth gets passed to neighboring gas molecules and global temperature goes up.

it will re-emit in a range according to the rules i can't recall, but here's a nice animation: - http://www.rkm.com.au/ANIMATIONS/carbon-dioxide-global-warming.html since the electromagnetic radiation absorbed and re-emitted by carbon dioxide are in fairly closely defined ranges, i think it's fair to use the word «colour».
