Question
This question is about polarization.
Distinguish between polarized light and unpolarized light.
Markscheme
light is said to be (plane) polarized if the electric field (vector) lies on one plane;
when light is unpolarized, the electric field (vector) lies on many planes/does not lie on a specific plane;
Examiners report
(a) was either very well answered or lacking in reference to the electric field.
