PROBLEM TO BE SOLVED: To solve the problem wherein a sensor becomes complicated, large and expensive, and a measuring device also becomes large and expensive, due to requiring fairly high-degree knowledge and skill for its handling and measurement, since matching oil and a prism must be ...
Minimum angle of deviation. It turns out that we can determine the refractive index of a transparent material by shaping it in the form of an isosceles prism and then measuring its minimum angle of deviation. With reference to Figure 1, the relationship between the refractive index n, the pri...
The prism coupler, known from experiments on integrated optics, can be used to determine the refractive index and thickness of a light-guiding thin film. B... M.S. Ab-Rahman,M.H.M. Zaman - 《Australian Journal of Basic & Applied Sciences》 被引量: 6发表: 2009年 Electrical and optical...
We measured the top angle of triangular prism, and the different angles of minimum deviation according to different monochromatic light traveling through the prism, then calculated the refractive index of prism. In the visible light area, the refractive index depending on light wavelength was in ...

A cross mark at the bottom of an empty vessel is focussed with the help of a vertical microscope. Now water (refractive index = \(\frac{4}{3}\)) is poured in the vessel. The height of water in the vessel is 4 cm. Another lighter liquid which does not mix with water and whose ...
: a prism made by combining two or more prisms of different refractive index so designed and placed that a ray of white or other nonhomogeneous light passing through the prism is deviated but not dispersed into a spectrum compare amici prism ...
Prism glasses are lenses which deflect light and therefore, can correct some ophthalmic conditions most notably ocular misalignment. Issues of Concern In optics, a prism is a device that uses refraction to change the direction of light. In nearly all applications, the refractive index of a prism...
(6)npnm=sin[(δmin+γ)/2]sin(γ/2)andsinα1=npnmsin(γ/2) are valid, from which the refractive index relative to the surrounding medium can be evaluated very easily. The simplicity of the numerical calculations for this special situation was the main motive for its application. Today,...
