One way to produce a beam of polarized light with intensity I and polarization angle 0 would be to pass unpolarized light with intensity Io through a polarizer whose transmission axis is oriented such that OTA = 0. How large must Io be if the transmitted light is to have intensity I?(Figure 3) Express your answer as a decimal number times the symbol I. For example, if Io = (1/4)I, enter 0.25 * I. ? Io =

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.
