Final answer:
When two polarizing filters are aligned parallel, all light passes through; if they are perpendicular, no light passes. The outcome depends on the relative orientation of the filters.
Step-by-step explanation:
The question involves the concept of polarizing filters used in physics. The filters modify the direction of light polarization, and when multiple polarizing filters are used, the outcome depends on their relative orientation. When two polarizing filters are aligned with each other, or parallel, all the light that is polarized by the first filter can pass through the second one. If the second filter is rotated, only the component of light that is parallel to the axis of the second filter can pass through. When the two filters are perpendicular to each other, no light passes through the second filter , which illustrates these different scenarios and the impact on light passage
