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...
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...

A monochromatic laser beam of intensity Io = 659 W/m2 is polarized in the y-direction and propagates in the positive z-direction. This beam is incident upon a quarter-wave plate whose fast axis makes an angle of 45 degrees with the x-axis as shown. Following the quarter-wave plate are two polarizers; the transmission axis of the first polarizer is aligned with the x-axis, while the transmission axis of the second polarizer makes an angle of θ1 = 72 degrees with the...

Experiment I: Malus' Law Questions The orientation of these polarizing filters can't be measured with great accuracy because they re not marked off in small increments. Estimate the maximum uncertainty in measuring @ in this experiment. Justify your estimate. 1 with theory. Let's assume your 21 From your data table, choose the trial in poorest agre 1/1 measurement was accurate, but that the angle was not accurate. Calculate the angle that would theoretically yield this value of 1/1 measured angle....
