Document Summary

Table of contents (1) retardation plates (2) production and analysis of plane, circularly and elliptically polarized light, By retardation plates (3)experimental arrangements for the production of polarized light (4) application of retardation plates (5)malu"s law (6) magnetic rotary polarization (7) frequently asked questions with answers. These plates are extremely helpful to deliver different sort of polarized light and convert one kind of polarized light to other. The amount of retardation can be communicated as birefringence times thickness birefringence ( o- e) changes with temperature and wavelength. How to produce plane polarized light by reflection. Plane-polarized light (utilized in the examination of enantiomers) is created by an instrument called a polarimeter (polariscope) and passes through a polarimeter tube holding either the liquid enantiomer or its solution. A circularly polarized wave can transform into one of two feasible senses. Circular polarization is an exceptional case of elliptical polarization.

DUE DATE: 12 00 noon Monday. Dec 6. 2010. The problems on this assignment are quite word because strong direction is being given to Students in how to proceed. Two problems will be selected at random for marking. Percentage polarization. It is useful to characterize partially polarized light in terms of its "percentage polarization". A light beam of constant intensity Io. is allowed to fall at normal incidence on an "ideal linear polarizer" (a linear polarizer is "ideal" if it panes all light polarized parallel to the polarizer's axis, and stops all light polarized perpendicular to that axis.) As the ideal polarizer is rotated continuously (see Figure 8.1; about an axis perpendicular to its plane, the transmitted intensity I passes through successive maximum and minimum values (denoted by I max and I min). The percentage polarization of the incident light is denned to be Find the percentage polarization measured in this way for the following light beams: "Unpolarized natural light" tor which I max = I min = Io/2. A beam of light. Initially unpolarixed. that has been passed through an ideal linear polarizer before being measured for percentage polarization. A beam of light, initially unpolarizcd, that has been passed through a non-ideal polarizer that (in terms of light intensity) transmits 70% of light polarized parallel to its polarizing axis and 20% of light polarized perpendicular to its polarizing axis. Circularly polarized light. (Circular polarization means that at any given fixed observation point In the beam, the E-vector has constant magnitude but rotates at the frequency of the electric field oscillations so that the tip of the vector describes a circle in the zy plane (perpendicular to the light ray at the point in question). Elliptically polarized light for which the tip of the E-vector moves on an ellipse in the x y plane, defined by where Ax and Ay are the amplitudes of the oscillating Ex and E y components of the electric field vector, and is the phase difference between those oscillations. NOTE: Do your calculation for the special case Ax = 2Ay and e =pi / 2. [(8.2) taxes a particularly simple form when e = pi / 2.]

If plane-polarized light is sent through two polarizers, the first at 45° to the original plane of polarization and the second at 90° to the original plane of polarization, what fraction of the original polarized intensity passes through the last polarizer?

(a) 0 (b)

\frac{1}{4}

(c)

\frac{1}{2}

(d)

\frac{1}{8}

(e)
