More than one analyzer can be used in a setup like that in the drawing, each analyzer following the previous one.
Suppose that the transmission axis of the first analyzer is rotated 33° relative to the transmission axis of the
polarizer, and that the transmission axis of each additional analyzer is rotated 33° relative to the transmission axis
of the previous one. What is the minimum number of analyzers needed for the light reaching the photocell to have
an intensity that is reduced by at least a factor of 100 relative to that striking the first analyzer?

The drawing shows an edge-on view of the solar panels on a communications satellite. The dashed line specifies
the normal to the panels. Sunlight stikes the panels at an angle with respect to the normal. If the solar power
impinging on the panels is 1500 W when = 61°, what is it when = 18°?
