Polarised light!
Yes, light is electromagnetic, whether it is polarized or not.
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 !!

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
Animals use light primarily for regulating their circadian rhythms, which help them coordinate their daily activities. Many animals also use light for vision, to find food, avoid predators, and communicate with each other. Additionally, some animals use light cues for navigation, such as following the sun or stars.
They dont tell time. Their animals silly. :)
No, animals cannot use photosynthetic pigments to produce energy through photosynthesis like plants can. Animals obtain energy by consuming organic matter, either directly through eating plants or other animals.
Monochromatic light consists of a single wavelength or color, while polarized light has its electric field vibrations restricted to a single plane. Monochromatic light can consist of multiple polarized components, but not all polarized light is monochromatic.
They use coal and animals skin
Well Bees and Vipers ,and Scorpians are just a few animals refering to this question .
