Final answer:
Polarizing filters work by allowing light with an electric field parallel to the polarization axis to pass through. At an angle of 45°, light intensity is reduced to 50%, and at 71.6° intensity is reduced to 10%. Furthermore, at 18.4° the intensity is 90% of the original value, illustrating the symmetry in polarization effects.
Step-by-step explanation:
The student's question appears to be mixing the concept of a 'polarizing movie' with an actual physics principle related to polarizing filters. The provided information primarily discusses how polarized lenses work by reducing the intensity of light at certain angles. To clarify, when using polarizing filters or lenses, an angle of 45° will reduce the intensity of light to 50% of its original value. At an angle of 71.6°, which is just 18.4° away from 90°, the light's intensity is nearly blocked entirely, demonstrating the intensity to be 10% of the original. Conversely, at an angle of 18.4°, the intensity is reduced to 90% of the original value, indicating a symmetry in the behavior of polarization with respect to angle changes.
