1.   Diamond absorbs infrared radiation by a slightly more complex process.

2.   Antarctica is excellent for such observations because the air is thin and dry and does not strongly absorb microwave radiation.

3.   Because the air at the South Pole is so dry and thin it scarcely absorbs infrared radiation.

4.   Clouds were supposed to bounce incoming sunlight away and absorb infrared radiation rising from below.

5.   Ingredients like PABA, oxybenzone and cinnamates are examples of chemicals that can absorb ultraviolet radiation.

6.   Now companies like Wavelength Technologies are making cell phone sheaths designed to absorb the radiation emitted by both the phone and its antenna.

7.   No two substances absorb infrared radiation exactly the same way, he said.

8.   One theory consistent with this idea is based on the fact that amino acids tend to decompose when they absorb ultraviolet radiation.

9.   Soot is dark, and absorbs solar radiation.

10.   The resulting spectrum displays peaks that correspond to the wavelengths at which the substance has absorbed radiation.
