Photochemical stability refers to the ability of a substance to maintain its chemical structure and properties when exposed to light, particularly ultraviolet (UV) radiation. Materials with high photochemical stability do not undergo significant degradation or reactions when irradiated, making them suitable for applications in environments with high light exposure. This stability is crucial in fields such as materials science, Photography, and the development of long-lasting pigments and dyes. In contrast, substances with low photochemical stability may degrade, discolor, or lose functionality when exposed to light.

Stark-Einstein's law of photochemical equivalence states that each photon absorbed or emitted in a photochemical reaction is associated with the activation of one molecule. This law helps to explain the relationship between light energy and the number of molecules undergoing photochemical reactions.

The heat outside in the summer makes the chemicals in photochemical smog go higher.
Photochemical smog can occur most anywhere. London-type smog comes from factories and the burning of coal and fossil fuels, where photochemical smog comes from hydrocarbons and nitrogen oxides mixing with sunlight.
Photochemical smog is a type of smog made when hydrocarbons and nitrogen oxides mix with sunlight.
No, rusting of iron is not a photochemical process. Rusting is a chemical reaction that occurs in the presence of moisture and oxygen, leading to the formation of iron oxide. Photochemical processes involve light as a driving force for chemical reactions.
Photochemical smog is formed when sunlight reacts with pollutants like nitrogen oxides and volatile organic compounds from vehicle emissions. This reaction forms ground-level ozone and other harmful pollutants. Photochemical smog can cause respiratory issues, eye irritation, and damage to vegetation.
