2. UV curing - Wikipedia

   en.wikipedia.org/wiki/UV_curing

   UV curing (ultraviolet curing) is the process by which ultraviolet light initiates a photochemical reaction that generates a crosslinked network of polymers through radical polymerization or cationic polymerization. [1] UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and ...

3. Photopolymer - Wikipedia

   en.wikipedia.org/wiki/Photopolymer

   A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum. [1] These changes are often manifested structurally, for example hardening of the material occurs as a result of cross-linking when exposed to light.

4. Photoinitiator - Wikipedia

   en.wikipedia.org/wiki/Photoinitiator

   In chemistry, a photoinitiator is a molecule that creates reactive species (free radicals, cations or anions) when exposed to radiation (UV or visible). Synthetic photoinitiators are key components in photopolymers (for example, photo-curable coatings, adhesives and dental restoratives).

6. Dental curing light - Wikipedia

   en.wikipedia.org/wiki/Dental_curing_light

   A dental curing light is a piece of dental equipment that is used for polymerization of light-cure resin-based composites. [1] It can be used on several different dental materials that are curable by light. The light used falls under the visible blue light spectrum. This light is delivered over a range of wavelengths and varies for each type of ...

7. Michelson–Morley experiment - Wikipedia

   en.wikipedia.org/wiki/Michelson–Morley_experiment

   For instance, the Fizeau wheel could measure the speed of light to perhaps 5% accuracy, which was quite inadequate for measuring directly a first-order 0.01% change in the speed of light. A number of physicists therefore attempted to make measurements of indirect first-order effects not of the speed of light itself, but of variations in the ...
