"Photochemical" Meaning
Relating to or produced by the interaction of light with chemicals, or caused by a chemical that has been exposed to light.
"Photochemical" Examples
Examples of usage:1. In the field of environmental science, photochemical reactions are an essential component in the formation of ground-level ozone and smog through the interaction of sunlight with pollutants such as nitrogen oxides and volatile organic compounds (VOCs).2. The process of silver halide photographic paper exposure is a classic example of photochemical reaction, where light hitting the silver halide creates a latent image that is then developed to produce a visible photograph.3. Some sunscreens work through photochemical screens that absorb or scatter UV radiation, preventing it from penetrating the skin where it could trigger these adverse reactions, such as premature aging and even skin cancer.4. Photochemical smog can be a critical concern in urban areas with heavy vehicle traffic, as the high concentration of hydrocarbons, carbon monoxide, and nitric oxides in car exhaust can combine with sunlight to form harmful air pollutants.5. Researchers in materials science are studying photochemical methods to produce nanomaterials, which can exhibit advantageous properties not found in their bulk counterparts, by manipulating nanoscale structures and surface interactions under specific light conditions.

Photobiotic
I couldn't find the word "photobiotic" in any English dictionary or resource. It's possible that it's a made-up or non-standard term.However, I can try to break down the word into its components to see if I can guess what it might mean."Photo" comes from the Greek word for "light", and "biotic" comes from the Greek word for "living thing".So, if I had to guess, I would say that "photobiotic" might relate to living things that interact with or are affected by light in some way.
Photobleaching
Photobooths
Photobooths are small, enclosed booths containing cameras and lighting that allow individuals or groups to take multiple photos by interacting with cameras and lighting, usually on a roll of film or digital prints produced instantly.
Photocatalysis
Photocatalysis is a chemical reaction that is initiated and sustained by light or photons. It involves the use of a catalyst, typically a semiconductor material, to accelerate a chemical reaction when exposed to light. In this process, the catalyst absorbs light energy, which triggers a series of chemical reactions that result in the formation of reactants or products.The most common example of photocatalysis is hydrogen production from water using titania (titanium dioxide, TiO2) as the photocatalyst. When light with sufficient energy hits the titania particles, it excites the electrons, which then react with water to produce hydrogen gas and oxygen.Photocatalysis has various applications, including:1. Water splitting: Producing hydrogen fuel from water using solar energy2. Air purification: Decomposing pollutants and toxic emissions from vehicles and industrial processes3. Self-cleaning surfaces: Reducing stains and bacterial growth on surfaces4. Cancer treatment: Targeting and killing cancer cells using photodynamic therapy5. Environmental remediation: Removing contaminants from soil, air, and water.

Photochromy
Photochromy is a phenomenon where a colorless or light-colored material changes color when exposed to light, particularly ultraviolet (UV) radiation, and reverts back to its original color when the light source is removed. This change in color is reversible and can occur multiple times.
