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 prism. ‘The Nicol prism is made up from two prisms of calcite cemented with Canada balsam.’ ‘The result is a transparent birefringent crystal, known as a Nicol prism, which effective separates polarized light at the interface between the two crystal halves.’ polarizingprismto be invented, in 1828 byWilliam Nicol(17701851) ofEdinburgh. It consists of arhombohedralcrystal ofIceland spar(a variety ofcalcite) that has been cut at an angle of 68 with respect to the crystal axis, cut again diagonally, and then rejoined as shown using, as a glue, a layer of William Nicol Principle When an unpolarized beam enters the noun. A device for producing plane-polarized light, consisting of two pieces of optically clear calcite or Iceland spar cemented together with Canada balsam in the shape of a prism. ‘The Nicol prism, which is made entirely of calcite, a doubly refracting mineral, isolates one beam cleanly.’.

Assertion: Nicol prism is used to produce and analyse plane polarised light. Reason: Nicol prism reduces the intensity of light to zero. camera. Ask your next
