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...

A beam of partially polarized light can be considered to be a mixture of polarized and unpolarized light. Suppose a beam of partially polarized light is sent through a polarizing filter. The polarization direction of the filter can be changed by rotating it. As the filter is rotated through 360 degrees, we observe that the transmitted intensity varies from some minimum value Imin to a maximum value of 7.0 times Imin. What fraction of the intensity of the original beam...
