  2. Deck prism - Wikipedia

    en.wikipedia.org/wiki/Deck_prism

    The deck prism laid flush into the deck, the glass prism refracted and dispersed natural light into the space below from a small deck opening without weakening the planks or becoming a fire hazard. In normal usage, the prism hangs below the overhead and disperses the light sideways; the top is flat and installed flush with the deck, becoming ...

  3. Dispersive prism - Wikipedia

    en.wikipedia.org/wiki/Dispersive_prism

    A ray trace through a prism with apex angle α. Regions 0, 1, and 2 have indices of refraction, , and , and primed angles ′ indicate the ray's angle after refraction.. Ray angle deviation and dispersion through a prism can be determined by tracing a sample ray through the element and using Snell's law at each interface.

  4. Base (topology) - Wikipedia

    en.wikipedia.org/wiki/Base_(topology)

    In mathematics, a base (or basis; pl.: bases) for the topology τ of a topological space (X, τ) is a family of open subsets of X such that every open set of the topology is equal to the union of some sub-family of .

  5. Parallelepiped - Wikipedia

    en.wikipedia.org/wiki/Parallelepiped

    Any of the three pairs of parallel faces can be viewed as the base planes of the prism. A parallelepiped has three sets of four parallel edges; the edges within each set are of equal length. Parallelepipeds result from linear transformations of a cube (for the non-degenerate cases: the bijective linear transformations).

    For All Mankind is an American science fiction drama television series created by Ronald D. Moore, Matt Wolpert, and Ben Nedivi and produced for Apple TV+.The series dramatizes an alternate history depicting "what would have happened if the global space race had never ended" after the Soviet Union succeeds in the first crewed Moon landing ahead of the United States.

  8. Amici roof prism - Wikipedia

    en.wikipedia.org/wiki/Amici_roof_prism

    An Amici roof prism, named for its inventor, the Italian astronomer Giovanni Battista Amici, is a type of reflecting prism used to deviate a beam of light by 90° while simultaneously inverting the image. It is commonly used in the eyepieces of telescopes as an image erecting system. It is sometimes called an Amici prism or right angle roof ...

  9. Minimum deviation - Wikipedia

    en.wikipedia.org/wiki/Minimum_deviation

    In a prism, the angle of deviation (δ) decreases with increase in the angle of incidence (i) up to a particular angle.This angle of incidence where the angle of deviation in a prism is minimum is called the minimum deviation position of the prism and that very deviation angle is known as the minimum angle of deviation (denoted by δ min, D λ, or D m).
