2. Dispersive prism - Wikipedia

   en.wikipedia.org/wiki/Dispersive_prism

   Dispersive prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow ). Different wavelengths (colors) of light will be deflected by the prism at different angles. [ 1] This is a result of the prism material's index of refraction ...

3. Prism (optics) - Wikipedia

   en.wikipedia.org/wiki/Prism_(optics)

   Prism (optics) A familiar dispersive prism. An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base ...

4. Opticks - Wikipedia

   en.wikipedia.org/wiki/Opticks

   Opticks: or, A Treatise of the Reflexions, Refractions, Inflexions and Colours of Light is a collection of three books by Isaac Newton that was published in English in 1704 (a scholarly Latin translation appeared in 1706). [ 1] The treatise analyzes the fundamental nature of light by means of the refraction of light with prisms and lenses, the ...

5. Dispersion (optics) - Wikipedia

   en.wikipedia.org/wiki/Dispersion_(optics)

   A compact fluorescent lamp seen through an Amici prism. In optics and in wave propagation in general, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency; [ 1] sometimes the term chromatic dispersion is used for specificity to optics in particular. A medium having this common property may be termed a ...

6. History of spectroscopy - Wikipedia

   en.wikipedia.org/wiki/History_of_spectroscopy

   History of spectroscopy. Light separated into a spectrum by refraction through glass prism. Colour dispersion angles exaggerated for visualisation. Modern spectroscopy in the Western world started in the 17th century. New designs in optics, specifically prisms, enabled systematic observations of the solar spectrum.

7. Prism spectrometer - Wikipedia

   en.wikipedia.org/wiki/Prism_spectrometer

   A prism spectrometer is an optical spectrometer which uses a dispersive prism as its dispersive element. The prism refracts light into its different colors ( wavelengths ). The dispersion occurs because the angle of refraction is dependent on the refractive index of the prism's material, which in turn is slightly dependent on the wavelength of ...

8. Science and inventions of Leonardo da Vinci - Wikipedia

   en.wikipedia.org/wiki/Science_and_inventions_of...

   Some of his smaller inventions entered the world of manufacturing unheralded. As an engineer, Leonardo conceived ideas vastly ahead of his own time, conceptually inventing the parachute, the helicopter, an armored fighting vehicle, the use of concentrated solar power, the car and a gun, [ 1] a rudimentary theory of plate tectonics and the ...

9. Nicol prism - Wikipedia

   en.wikipedia.org/wiki/Nicol_prism

   Nicol prism. A Nicol prism is a type of polarizer. It is an optical device made from calcite crystal used to convert ordinary light into plane polarized light. It is made in such a way that it eliminates one of the rays by total internal reflection, i.e. the ordinary ray is eliminated and only the extraordinary ray is transmitted through the ...
