Phosphoric acid, two aluminium hydride, with graphite powder and mud
Some of the key wavelengths off the chemical bond are shown below. The C-N bond is easiest to break, and the C-H bond is the hardest. You can also see that ultraviolet radiation can cause many chemical bonds to break. The activation wave length of some polymers is listed below. The data in the following table show that different polymers have different maximum damage wavelengths, and often the maximum damage wavelength is called the maximum activation wavelength. At this particular wavelength of light, the polymer can crack at the fastest rate.
Of a chemical bond, there is a certain minimum energy for molecules can break chemical bonds between the atoms, the energy corresponding to a critical wavelength, can make the chemical bond breaking in the wavelength of light irradiation.
Sunlight filtered through the atmosphere to achieve visible light and a small amount of ultraviolet light (UV) on the earth's surface. UV light has a wavelength of 295nm and UV light accounts for only 5% of the sun. The energy of light is inversely proportional to the wavelength, and the shorter the wavelength, the higher the energy.
