Question
Certain sunglasses use a polarizing material to reduce the intensity of light reflected as glare from water or automobile windshields. What orientation should the polarizing filters have to be most effective?
a) The polarizers should not absorb either horizontal or vertical electric fields.
b) The polarizers should absorb both horizontal and vertical electric fields.
c) The polarizers should absorb light with its electric field vertical.
d) The polarizers should absorb light with its electric field horizontal.
Explanation / Answer
polarizers can absorb the light from either of the polarizing directions(vertical or horizontal).
as polarizers just passes the components in a single direction , the unpolarized light coming from the sun can not be fully blocked by a single polarizer, therefore only either direction of the electric field component can be blocked, which means only 1 of the component will pass through.
