Unpolarized light with intensity I0 is incident on two polarizers as sketched in the figure below. Suppose the angle between the axes of the two polarizers is ? =66
Homework Answers
Assuming that both polarizers are perfect, we use the law of Malus:
when the light is unpolarized, it may contain many types of
polarization, for different angles, then we take the average value
of 
to express the first polarization as a function of 
now use the law of malus for obtain the second polarization:
