What is the wavelength range,in nanometer,for infrared light? In what portion of this range does the earth receive IR from the s
andrezito [222]
  • The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter.
  • The sun emits mainly near-infrared which is mainly composed of wavelength below 4 micrometers.
  • The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers

Explanation:

The wavelength range of Infrared radiation is 700 nanometers to 1 millimeter. This also translates to a frequency range of 430 TeraHertz  to 300 Giga Hertz.

Because the sun is a star and is hot in comparison to earth and other planetary bodies, the bigger  range of infrared radiation it emits is in the near-infrared which is mainly composed of wavelength below 4 micrometers.

The earth's surface produces infrared radiation of the mid-infrared range while cooler substances will produce far-infrared range

The thermal range of infrared ranges between wavelengths 3.5 and 2.0 micrometers and is produced by black bodies.

Which of the following statements best describes why carbon can form a variety of organic compounds? Carbon atoms bond readily w
olga_2 [115]
Answer:
            <span>Carbon readily forms covalent bonds with other carbon atoms.

Explanation:
                   As we know approximately more than 95 % compounds, either isolated, discovered or synthesized belongs to organic compounds containing carbon atoms.
                  This great diversity of organic compounds is due to following facts.

1) Catenation:
                      Carbon has a peculiar behavior of self linkage. This self linkage of one carbon with another is called as catenation. In this way carbon can form a long chain of carbon atom. A branching can also take place when one carbon is bonded further to three of four carbon atoms.

2) Isomerism:
                     Secondly the carbon containing compounds show isomerism. In which molecular formula is same but structural formula is different. For example molecular formula C</span>₅H₁₂ can make following compounds,

                                a)  n-Pentane

                                b)  2-Methylbutane

                                c)  2,2-Dimethylpropane

3) Multiple Bonds:
                            Carbon can form multiple bonds i.e double bond like in alkenes and triple bonds like in alkyne. 

Due to these factors carbon gets very high number of opportunities to form large number of compounds.
