What is the meaning of Prism?

A polyhedron with parallel ends of the same polygonal shape and size, the other faces being parallelogram-shaped sides.

  1. An object having the shape of a geometrical prism (sense 1).
  2. A cutting (open passage at a level lower than the surrounding terrain, dug for a canal, railway, or road to go through) or an embankment shaped like a prism (sense 1) or a number of prisms, such that its volume can be easily calculated.
  3. A crystal in which the faces are parallel to the vertical axis.
  4. A transparent block in the shape of a prism (sense 1), typically with triangular ends, used to reflect or refract light.
    1. A spectrum produced by light being refracted through a prism.

A spectrum produced by light being refracted through a prism.

A retroreflector (device which reflects light back to its source with minimal scattering) which is usually attached to a surveying pole as a target for a total station which emits a light beam at the device and calculates how long it takes to be reflected back in order to measure distance.

A perspective that colours one's perception.
