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. Double-slit experiment - Wikipedia

   en.wikipedia.org/wiki/Double-slit_experiment

   Double-slit experiment. In modern physics, the double-slit experiment demonstrates that light and matter can satisfy the seemingly incongruous classical definitions for both waves and particles. This ambiguity is considered evidence for the fundamentally probabilistic nature of quantum mechanics. This type of experiment was first performed by ...

4. 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 ...

5. 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 ...

6. Beam splitter - Wikipedia

   en.wikipedia.org/wiki/Beam_splitter

   Beam splitter. Schematic illustration of a beam splitter cube. In practice, the reflective layer absorbs some light. A beam splitter or beamsplitter is an optical device that splits a beam of light into a transmitted and a reflected beam. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also ...

7. History of spectroscopy - Wikipedia

   en.wikipedia.org/wiki/History_of_spectroscopy

   His experiments demonstrated that white light could be split up into component colors by means of a prism and that these components could be recombined to generate white light. He demonstrated that the prism is not imparting or creating the colors but rather separating constituent parts of the white light. [6] Newton's corpuscular theory of ...

8. Dispersion relation - Wikipedia

   en.wikipedia.org/wiki/Dispersion_relation

   In a prism, dispersion causes different colors to refract at different angles, splitting white light into a rainbow of colors. In the physical sciences and electrical engineering, dispersion relations describe the effect of dispersion on the properties of waves in a medium.

9. Delayed-choice quantum eraser - Wikipedia

   en.wikipedia.org/wiki/Delayed-choice_quantum_eraser

   In the basic double-slit experiment, a beam of light (usually from a laser) is directed perpendicularly towards a wall pierced by two parallel slit apertures.If a detection screen (anything from a sheet of white paper to a CCD) is put on the other side of the double-slit wall (far enough for light from both slits to overlap), a pattern of light and dark fringes will be observed, a pattern that ...
