Q.What is Polarimeter?. A.It is a device used to measure the angle of rotation of plane of polarisation rotated by an optically active substance. Q.What is specific rotation?. A.Specific rotation of an optically active substance at a given temperature is the rotation in degrees of the plane of polarisation of incident polarized beam produced by one decimeter .Interview Questions on Polarimeter. P olarimetric methods are reliable and simple methods for determining and analyzing the structure of expensive and nonreplicable samples in macro, semi-micro, and microanalysis.. Pharmaceutical, chemical, essential oil, flavor, and food industries use polarimetry for quality control, process control, and research.
Half shade principle Optical rotatory power Optical activity Specific rotation Aim of the experiment To determine the specific rotation of an optically active substance by polarimeter. Apparatus required A Polarimeter Optically active substance (known weight) A measuring cylinder A beaker A scale Distilled water Sodium light source TheoryLaurent's half-shade polarimeter. When plane-polarised light passes through some crystals, the velocity of left-polarized light is different from that of the right-polarized light, thus the crystals are said to have two refractive indices, i.e. double refracting. . Just after the convex lens there is a Nicol Prism P which acts as a polariser .Polarimeter, Electric bulb with housing, sugar, balance, graduated cylinder and thermometer. . As shown in fig.1, Source is the Sodium Vapor lamp fitted in housing, P.Nicol, the polarizing Nicol, H, the Half shade device, A Nicol, the analyzing Nicol and Eye piece is the observing eye piece and solution is contained in the tube with glass end.

half shade polarimeter (or Bi-quartz polarimeter, as the case may be). Q. 2. What do you mean by specific rotation ? Ans. The specific rotation of an optically active substance at a given temperature for a given wavelength of light is defined as the rotation (in degrees) of plane of polarisation of incident5. While measuring the angles of rotation, the two halves of the half-shade plate should be equally bright. Failure to judge the equality of brightness will introduce errors. To minimize those errors, four readings should be taken for each concentration. Questions 1. How does polarized light differ from the ordinary light? 2. What is optic axis?Articles for tag: formula for specific rotation, how to calculate specific rotation, laurent's half shade polarimeter, polarimeter experiment, specific optical rotation interview questions, specific rotation, specific rotation and optical rotation, specific rotation calculator, specific rotation definition, specific rotation formula, specific rotation glucose, specific rotation in polarimeter . # Lab Viva , #Physics lab experiments, #Dr Mukesh Chandra Dimri, #Bi-Quartz Polarimeter, #viva Preparation#specific Rotation of Sugar Solution,, #Nicol Pr.

This video provides you the most important questions of the experiment - to determine the specific rotation of sugar solution using polarimeter.=====.Multiple choice questions: (1) The polarization is possible in _____ wave (a) transverse (b) longitudinal (b) water (d) mechanical (2) A _____ light is a wave in which the electric vector is everywhere confined to a single . Explain the construction and working of Half-shade polarimeter. 23. What is half shade polarimeter? Discuss it in .
A polarimeter consists of two Nicols termed as polariser and analyser. These can be rotated about a common axis and the substance for which the rotation is to be determined, is placed in a tube in between these two. The half shade plate is placed between the polariser and the solution tube (cf., Fig. 3).

With the help of half shade polarimeter, polarization can be studied as well as analyzed. For better accuracy in determination of specific rotation, half shade polarimeter is used which involves comparing the brightness of two halves in the field of viewStep 1: If the polarimeter is employing a half shade device, a monochromatic source should be used and if biquartz device is used then white light can be used. Step 2: Take the polarimeter tube and clean well both the sides such that it is free from dust. . 2 VIVA-VOCE QUESTIONS: Qu. What do you mean by polarization? Ans. The lack of symmetry .
