While you are looking through two polarizing sheets, one of the sheets is slowly rotated by 180 degrees. Which of the following might you see?

While you are looking through two polarizing sheets, one of the sheets is slowly rotated by 180 degrees. Which of the following might you see?


Initially, virtually no light gets through, but the light gets gradually brighter and is brightest after completing the 180 degree rotation.


Initially, much light gets through and it is very bright, but it gets gradually darker until virtually no light gets through after a 180-degree rotation.


Initially, virtually no light gets through, but the light gets gradually brighter and is brightest after completing 90 degrees of rotation. Then, the light begins to gradually get darker until virtually no light gets through after another 90 degrees of rotation (180 degrees total).


Initially, much light gets through and it is very bright, but it gets gradually darker until virtually no light gets through after a 90-degree rotation. Then, the light starts to get brighter again and is brightest again after 90 more degrees of rotation (180 degrees total rotation).


Some light gets through initially. You start rotating, and the lights grows dimmer. After 60 degrees of rotation, virtually no light gets through. You keep rotating, and the light starts getting brighter. After another 90 degrees of rotation (150 degrees total), the light is at a maximum, and then the light through the pair of polarizers begins to get dimmer for the remaining 30 degrees of rotation.

None of the above.
