Light absorption is a physical process; but the effects of the absorption may be chemical.
chemical reaction brought on by light ( latin: photo - light)
Photosensitization is a reaction to light that is mediated by a light-absorbing molecule, which is not the ultimate target.
When alcohol undergoes a chemical reaction, it can produce a colored substance due to the formation of new molecules with specific light-absorbing properties. This change in molecular structure can lead to the absorption and reflection of certain wavelengths of light, resulting in the perception of color.
Light Energy,Electrical Energy,Light and thermal energy
The energy provided by absorbing light can substitute for the heat energy that usually accelerates chemical reactions. More fundamentally, any endothermic chemical reaction can occur because an increase in entropy compensates for any heat absorbed by the reaction to make the free energy change negative.
Ozone is the chemical that absorbs UV light. It is present in the stratosphere.
6CO2+6H2O+light energy-->C6H12O6+6O2 Chemical reaction of Photosynthesis
The ability to produce heat and light in a chemical reaction is called combustion. It is a type of exothermic reaction where energy is released in the form of heat and light.
The decomposition reaction caused by light is called photolysis. This process involves the breaking down of a compound into simpler substances by absorbing light energy.
An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. It is the opposite of an endothermic reaction
Chemical energy can be converted into light energy through a chemical reaction involving compounds that emit light, such as in bioluminescence. This reaction releases energy in the form of light as a byproduct. Examples include fireflies producing light through a reaction involving luciferin and luciferase, or certain chemical light sticks activated by breaking and mixing two chemicals together to produce light.
its a chemical reaction. in addition to heat and light, a new gaseous substances are formed
