What is the meaning if "electromagnetic waves are polarised vertically"?

It means electric field vector of electromagnetic wave is oriented in vertical direction.
Say if vertical direction is z-axis then electric field is along z-axis but ofcourse sinusoidally varying its direction and magnitude.
In an unpolarized electromagnetic wave the electric field is radomly in all directions and isotopically distributed.
Just like plane polarised light or EMW we can have circularly, elliptically polarized electromagnetic waves

The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp. |
