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 linearly polarized beam of light of intensityI0 is propagating
in the +z direction and its direction of polarization makes an
angle of 74° with the x-axis (the angle between the initial
direction of polarization and the transmission axis of the first
polarizer is 16° as described below). Two linear polarizing sheets
are lined up perpendicular to the beam. The first sheet has its
transmission axis at an angle q 1 = 90° with respect to thex-axis.
The transmission axis...
