Light can be determined to be polarized if... A. rotation of a Polaroid disc changes the intensity of transmitted light B. blue light is scattered more than red light viewed through a Polaroid disc. C. a double refracting material produces two beams of light. D. a sugar solution absorbs light as if it were an opaque substance.
Because polaroid discs block out light of a certain directional polarization it is safe to assume that by rotating the disc you are therefore changing the angle of the light you are polarizing. So if there is light that is polarized like this ||||||||| and you have a disc thats like ==== then you will block the light. So by rotating the disc so that its like this \\ or /////// you are allowing more and more light in. A.
It is A. Polarized light is: - blocked by a polaroid filter if the plane of polarization is perpendicular to the polarization axis of the filter - transmitted by a polaroid filter if the plane of polarization is parallel to the polarization axis of the filter and partially transmitted for angles in between
