Question

what is photodegradation​

Answer 1

hey mate here is the answer

Photodegradation is degradation of a photodegradable molecule caused by the absorption of photons, particularly those wavelengths found in sunlight, such as infrared radiation, visible light, and ultraviolet light

Alteration of the materials by using light is known as photodegradation. Basically, photodegradation involves sunlight and air to act together. Photodegradation involves the process of oxidation (loss of electrons, increase in oxidation state) and hydrolysis (split of chemical bonds by adding water).

Photodegradation can destroy artefacts and the paintings and hence it is often not preferred. Photodegradation does not talk about the ageing or degradation of materials with the use of heat or infrared light. However, it does include the degradation that occurs in all of the ultraviolet light wavebands.

Answer 2

Explanation:

Photodegradation is usually oxidation and hydrolysis. This term is use for combined action of sunlight and air
