also how can polarized light be created?
Common light sources, like the sun, a fluorescent lamp or a candle flame, are not emitting polarized light. But when light from these sources shines on a polarizing filter, the transmitted light is polarized. For example, sunlight shining on a filter,such as that used in Polaroid sunglasses, becomes polarized light when transmitted. Hope this helps!
This Site Might Help You. RE: what's the difference between polarized and unpolarized light? also how can polarized light be created?
A light wave that is vibrating in more than one plane is referred to as unpolarized light. Light emitted by the sun, by a lamp in the classroom, or by a candle flame is unpolarized light. Such light waves are created by electric charges that vibrate in a variety of directions, thus creating an electromagnetic wave that vibrates in a variety of directions. See link for an image of what polarization does. It makes all lines go only one direction:
With a wave there is a direction up and down the wave goes, this direction is not constant. Polarized light is when all these waves are going up and down in the same direction, unpolarized light has them going in all directions. To polarize light you need a material that has thousands maybe millions lines that will only let one direction of polarization to go through. I am not sure they have this, i think they do i remember hearing something about it. Google it if you have to.
