Yes, light is electromagnetic, whether it is polarized or not.
Polarised light!
A polarized light vibrating in a single plane perpendicular to the direction of propagation is called plane polarised light.
In China Polarised Ray ban is made of Plastic Lens. If not polarised,than be glass lens. Any way you may feel light when wearing polarised plastic lens and feel a little heavy in glass lens. But polarised is easy to be scratched. So should be careful when wearing . Hope this can help you !!

Most of the EM spectrum is visible light.
The laser causes the stimulated emission of radiation. The light emitted is monochromatic and coherent,that is plane polarised. I imagine that spontaneous emission occurs in a Light emitting diode ,monochromatic but not polarised. Hope this is of help
Many insects navigate using polarized light; for example bees and ants. Some birds are also sensitive to light polarization.
Monochromatic means that it has only frequency. Polarized is definition for light which has its electric and magnetic vectors oscillating in a certain way (linearly polarized, elliptically and so on) but it might have many frequencies included. In the same time monochromatic light can be polarized.
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
Polaroid filters block light traveling in the horizontal plane. Essentially, the filter only allows light that's traveling vertically to get past the lens. Polaroid filters are often used on sunglasses.-----Polaroids are the collection of micro crystals that are used to control the propagation of light. As we all know, light is a wave that propogates with a speed of 3 x 108 m/s. It vibrates in all direction. If a light passes through a Polaroid, light polarised parallel is absorbed, and only the light polarised perpendicular are transmitted.
The plane polarised light passes through Sample the light Rotates through optical activity.the light rotate right side i.e.dextro rotatory or the light rotate left side i.e.leavo rotatory
