How can you tell if rzrz j:6a1n9c ,e3g6f nt9fg)hdpw xx8nl 85fa pair of sunglasses is polarizing or not?
参考答案: To determine if a pair of
sunglasses is polarizing or not, first find the glare (strong reflection) from
a light source on a horizontal non-metallic surface (water, tiled floor,
polished tabletop, top of car). Then look
at the reflection through the sunglasses and rotate them. If they are polarizing sunglasses, then there
should be orientations of the glasses that almost completely block out the
glare and other orientations that let 50% of the glare through. If they are not polarizing sunglasses, the
glare will be slightly diminished by the same amount at all orientations of the
glasses, but it will never completely go away.
