Question
![Learning Goal:
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.
Most natural light sources emit "unpolarized" light, perhaps better described as "randomly polarized" light. These light sources emit
numerous brief bursts of light whose polarization directions are unrelated, so on average the resulting beam has all polarization angles
equally represented. When unpolarized light with intensity Io passes through a polarizer, its intensity I is cut in half, regardless of the
orientation of the transmission axis of the polarizer:
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
ocillation of a wave is called the polarization of the
wave. The upper wave is described as polarized in the
+x direction whereas the lower wave is polarized in
the +y direction. In general, waves can be polarized
along any direction.
