This plug - in headset features noise reduction and a high quality speaker, not to mention the elimination of 99 % of
absorbed radiation from your wireless phone.
Unfortunately, many of the fabrics we wear, such as cotton, have chemical groups that
absorb radiation in that range.
But it is fundamental to understanding how a «greenhouse»
gas absorbs radiation, and fundamental to understanding why some of us think the whole global warming scare is a total scam.
The obvious conclusion is that if we are significantly changing how the planet
atmosphere absorbs radiation and we don't have a clue about the effects, then we should be very afraid.
It was only in the 1950s, when improved instruments showed more precisely how water and
CO2 absorbed radiation, that we reached a better understanding of its importance.
While its presence can be inferred from the gravitational pull it exerts on visible matter, the fact that it does not emit or
absorb any radiation makes it next to impossible to detect.
Even N2 and
O2 absorb radiation very weakly when they are in collision with any other molecule.
The photoluminescence material they
created absorbs the radiation from the sun, and converts the heat and light from the sun into an «ideal» radiation, which illuminates the photovoltaic cell and enables higher conversion efficiency.
That plastic mimics how biological
tissue absorbs radiation, and the LRO mission is the first time it will find use outside Earth's protective influence, Keller says.
However they are well mixed in the atmosphere and reach high levels due to their ability to
absorb radiation combined with intense collisional activity in the denser lower regions.
The process works like this: the ozone hole reduces the vertical stability of the S.H. troposphere, by making the air colder aloft (ozone
normally absorbs radiation, and the ambient air is colder when ozone in the lower stratosphere is absent).
«That's a very definite, instantaneous impact where you have this black
stuff absorbing radiation and helping enhance the melting,» says Quinn.
But, because the water vapor and CO2 spectra overlap, the total increase is actually only about 7 % since the water vapor is
now absorbing radiation previously absorbed by CO2.
