law: I = I0 cos²θ where I0 is the intensity of the polarized light beam just before entering the polarizer
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 D
One way to produce a beam of polarized light with intensity I and polarization angle would θ be to pass unpolarized light with intensity Io through a polarizer whose transmission axis is oriented such that θTA = 0. How large must Io be if the transmitted light is to have intensity I?

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...

When a beam of light passes through a pair of polarizing filters (polarizer and analyzer), the intensity of the transmitted light is a maximum when the transmission axes of the polarizer and analyzer are parallel to each other (θ = 0° or θ= 180°) and zero when the axes are perpendicular to each other (θ = 90°). For any value of theta between 0° and 90° the transmitted intensity is given by I = Ii cos2(θ) where Ii is the...
