A linearly polarized electromagnetic wave has an average intensity of 324 W/m2. This wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). Polarizer A is oriented with its transmission axis at an angle of θ1 = 40.0° with the incident electric field. Polarizer B has its axis at an angle of θ2 = 70.6° with the incident electric field, as shown in the figure. What is the average intensity of the...
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.)
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)
Vertically polarized light with intensity Io is incident on a horizontal polarizer. What is the intensity of the outgoing wave? A polarizer oriented 45 degrees with respect to the light is placed in front of the horizontal polarizer. What is the intensity of the outgoing light?
law: I = I0 cos²θ where I0 is the intensity of the polarized light beam just before entering the polarizer, I is the intensity of the transmitted light beam immediately after passing through the polarizer, and is the angular difference between the polarization angle of the incident beam and the transmission axis of the polarizer. After passing through the polarizer, the transmitted light is polarized in the direction of the transmission axis of the polarizing filter. Part DOne way to produce a beam of polarized...
To understand polarization of light and how to use Malus's law to calculate the intensity of a beam of light after passing through one or more polarizing filters. The two transverse waves shown in the figure(Figure 1) both travel in the +z direction. The waves differ in that the top wave oscillates horizontally and the bottom wave oscillates vertically. The direction of oscillation of a wave is called the polarization of the wave. The upper wave is described as polarized...
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...

question 7 and 8 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...
