When an ordinary ray of light is passed through a calcite crystal, it is broken up into two rays: An ‘Ordinary ray’ which is polarized and has its vibrations perpendicular to the principle section of the crystal and. An extra-ordinary ray which is polarized and whose vibration is parallel to the principle section of the prism.If by some optical means, one of the About this video----In this vedio we will discuss about:-1.

the ordinary ray is eliminated and only the extraordinary ray is transmitted through the prism. So it works on principle of double refraction.

When the unpolarized light falls on the first Nicol, the intensity of the light halves and When this polarized light falls on the next Nicol prism at an a Principle : POLARISATION. Observing various phenomenon exhibited by light ( a) Linear (is obtained by a linear polarizer e.g. Nicol prism, Tourmaline crystal). principle is used in a Nicol prism which consists of a calcite crystal cut in such a way that for the beam, for which the sandwiched material is a rarer medium, the In Nicol Prism, ordinary ray is eliminated by the principle of total internal reflection so that the extraordinary ray is transmitted out as plane polarised light.

2. It is cut into two halves along the diagonal so that their face angles are 72° and 108°. Nicol Prism 3. Assertion: Nicol prism is used to produce and analyse plane polarised light.
Reason: Nicol prism reduces the intensity of light to zero.

Nicol prisms were first used to measure the polarization angle of birefringent compounds, leading to new developments in the understanding of interaction between polarized light and crystalline One of the ﬁrst prism polarizers to utilize a birefringent crystal was developed by William Nicol in 1828 and is known as the Nicol prism. The Nicol prism shown in Fig. 3.2 is constructed from negative uniaxial calcite, where n o = 1:6584 and n e = 1:4864 for = 589:3 nm. Calcite is a widely used material because of In a petrological microscope two Nicol prisms are provided, the first, the polarizer, mounted below the stage, and the second, the analyzer, set in the tube above the objective. Polaroid is an inexpensive substitute for Nicol prism, which operates on the same principle.
