Question

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 I_min to a maximum value of 7.0 times I_min. What fraction of the intensity of the original beam is associated with polarized light? Please explain everything you do

Answer 1

oso Transmitted infensity = (700 timesjo (5 min let the intensities of the unpokarized Light and polarized tight be "I and a Respectively, & After going through the polarizing filter The intensity of the unpotarized light will be (o.s) and intensity of the polarized light will have a value between 10¢ al. maximum Intensity of Beam = 7 minimum intensity of Brom > forstand= 7 7 Oosta = 3.5 las 3 Bo fraction of the rafensity of the original beam - SÅ associated with the beam's polarized light 7 tita)= tits] =$0.75),
