Answer: If the second polarizing filter is rotated by 45°, only the component (parts of the light beam) of the light parallel to the second filter's axis is passed.

Explanation: Polarization is the process of converting unpolarized light to polarized light.

Polarized light waves are light waves travel in a single plane.

If two polarizing filters are applied to a light wave,

-If the axes of the first and second filters are aligned in a parallel form, it would cause all of the polarized light passed by the first filter to also pass by the second.

- If the second polarizing filter is rotated by an angle of about 45°, only the parts of the light beam parallel to the second filter's axis is passed.

- When the axes of the polarization filter are perpendicular, no light is passed by the second filter.
