Three polarizing filters are stacked with the polarizing axes of the second and third at 58.5 ∘ and 90.0∘, respectively, with that of the first. An unpolarized light of intensity I0 is incident on the stack.
B. Find the intensity of light emerging from the second filter.
C. Find the intensity of light emerging from the third filter.
D.If the second filter is removed, what is the intensity of the light emerging from the first filter?
E. If the second filter is removed, what is the intensity of the light emerging from the last filter?

A horizontal beam of unpolarized light is incident on a stack of three polarizing filters with their polarization axes oriented, in sequence, 30◦, 60◦ and 90◦ clockwise from the vertical. The intensity of the light emerging from the stack is measured to be 275 W/m2. What is the intensity of the emerging light (in W/m2) if the middle polarizing filter is removed?

Two polarizing sheets have their transmission axes crossed so that no light gets through. A third sheet is inserted between the first two so that its transmission axis makes an angle θ with the transmission axis of the first sheet. Unpolarized light of intensity I0 is incident on the first sheet. Suppose that the middle sheet is replaced by two polarizing sheets. The angles between the transmission axes of the second, third and fourth sheets in the stack make angles...
