Question

Which of the following statements about polarized materials is NOT true?

Two polarized filters that have polarizing axes parallel to each other will block all the light passing through them.

Polarized materials have molecules that allow light to pass through them in only one direction.

Two sheets of polarized materials will block all light through them if they are placed so that their polarizing axes are perpendicular.

The alignment of molecules allowing only one direction of light in the material is called its polarizing axis.

Answer 1

The incorrect statement about polarized materials is that two polarized filters with their axes parallel will block all light, while in reality, they pass all light that is polarized along the axis.

Step-by-step explanation:

• The statement about polarized materials that is NOT true is: "Two polarized filters that have polarizing axes parallel to each other will block all the light passing through them."
• This statement is incorrect because when two polarizing filters are aligned with their axes parallel, all of the polarized light that passes through the first filter will also be passed by the second filter.
• If the second polarizing filter is rotated, only the component of the light parallel to the second filter's axis is passed.
• However, it is when the axes of two polarizing filters are perpendicular to each other that they will block all the light passing through them.
• Polarized materials have molecules that are aligned in such a way that they only allow light to pass through in one direction, which is known as the polarizing axis.
