Incredible and fun facts to explore

Polarized Light facts

While investigating facts about Polarized Light Microscopy and Polarized Light Definition, I found out little known, but curios details like:

Reindeer are one of the only mammals that can see UV light, allowing them to see lichen, polar bears against the snow, and urine trails

how polarized light is produced?

His doctoral thesis was on the plane polarization of light and the phosphorescence and absorption of light by crystals.

What is linearly polarized light?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is the difference between polarized and unpolarized light. Here are 20 of the best facts about Polarized Light Meaning and Polarized Light Microscope I managed to collect.

what is plane polarized light?

  1. Dung Beatles navigate using compass neurons in their brains while rolling dung balls. During the day, the neurons respond to the position of the sun, and at night they respond to polarized light. In absence of polarized light-like on a moonless night, they use the milky way.

  2. With practice and good vision, humans can perceive polarization of visible light.

  3. Although they look white, their fur is transparent. When light bounces back from the fur, result is a white color, combination of all colors. Thanks to the white color, they blend with their environment easily.

  4. In 1847 he entered the University of Edinburgh and his experiments with polarized light led to his discovery of photoelasticity as a means of determining the stress distribution in physical objects.

  5. There are bugs, that reflect only circular polarized light, and when viewed through circular polarizer - appear colorless.

  6. Polar bears' fur is not white. It's actually pigment-free and transparent and reflects visible light

  7. Cuttlefish has W-shaped pupils and ability to see polarized light (unlike humans).

  8. The Mantis Shrimp can see UV and Infrared, differentiate Polarized Light and move it's eyes independantly

  9. Polar bears actually have colorless fur and black skin. This allows the bear to stay warm in winter as light passes through the hair and gets absorbed by the skin, while retaining the heat in the fur.

polarized light facts
What is the difference between light that is polarized and light that is not?

Why is reflected light polarized?

You can easily fact check why is reflected light horizontally polarized by examining the linked well-known sources.

Adding extra polarizing filters at angles less than 45 degrees to the next filter will increase how much light gets through the filters

Humans can perceive the polarization of light - source

Polar bears fur is actually transparent. It only appears white, because it reflects visible light. - source

Mantis Shrimp can see differences in polarized light which in turn allows them to see cancer cells.

Polar lights (northern/southern lights) are a result of something called a solar wind, which consists of particles that are ejected from the sun that reach the earth's atmosphere. - source

Why is light polarized when reflected?

We have the ability to detect light polarization with our eyes alone

How polarized light microscopy works?

Humans can detect the polarization of light

Polar Bears are nearly invisible to infrared light so only their faces and breath show up with night vision glasses.

This is our collection of basic interesting facts about Polarized Light. The fact lists are intended for research in school, for college students or just to feed your brain with new realities. Possible use cases are in quizzes, differences, riddles, homework facts legend, cover facts, and many more. Whatever your case, learn the truth of the matter why is Polarized Light so important!
