IP Optically active molecules have the property of rotating the direction of polarization of linearly polarized light. Many biologically important molecules have this property, some causing a counterclockwise rotation (negative rotation angle), others causing a clockwise rotation (positive rotation angle). For example, a 5.00 gram per 100 mL solution of l-leucine causes a rotation of -0.550∘; the same concentration of d-glutamic acid causes a rotation of 0.620 ∘ . Part A) Find the transmitted intensity for each of these solutions when placed between crossed polarizers. The incident beam is unpolarized and has an intensity of 11.0 W/m2 .

For the polarizers in the figure, suppose the incident light is linearly polarized, the transmitted intensity (through both polarizers) is 0.15×I0, and the axis of the second polarizer makes an angle θ=50° with the axis of the first polarizer. What is the angle (in degrees) the initial direction of polarization makes with the first polarizer? (Insert the number of degrees without unit.)
5. A plane, linearly polarized light wave, with intensity, Io, is transmitted through a system of perfect linear polarizers (we assume that all light is transmitted in the transmission direction but in the perpendicular direction all light is absorbed). Give for the following systems of polarizers and transmission directions the total transmitted intensity: (angles are measured in the same direction and relatively to the polarization direction of the incident light) a) one at 90° angle b) two at the angles...
Linearly polarized light propagating along the y-direction is incident on a polarizer whose axis is parallel to the 2-direction. If the intensity of the transmitted light is equal to 33% of the incident intensity, what is the angle of polarization (in degrees) between the incident light and the z-axis? (Insert the number of degrees without unit)

Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
