Multi-read content what color are polar bears fur

Earlier this year we asked youWhat color do you think polar bears are?? The answer is quite unexpected! Polar bears’ fur is actually almost transparent and their skin is black!So how do they look white?We asked some of the best scientific minds to explain it to us. Her answers take us deep into the world that makes up polar bear fur and explores optics, the science of light and vision.

What makes a polar bear fur?

 
Apolar bearsThe coat has two coats: an outer layer consisting of long guard hairs (5-15 cm); and a thick undercoat composed of shorter hairs.

These guard hairs are mostly transparent or transparent in color, but thanks to some special properties that work for cool optical tricks, these hairs are white. Here are the distinctive features of guard feathers: they are coarse, tapered (to a certain point in length), and have a hollow core filled with air; they are made of a protein called keratin; they have light-scattering particles within them; and between each strand of hair are tiny grains of salt.

The power of optics!

 
All of these special qualities of polar bear guard hairs work together with the power of light to make polar bears white. That’s how it’s done:

charisma

When the sun’s rays hit the polar bear’s transparent protective fur, some of this light energy is transferred to the fur and trapped there. This energy is reflected on the inside of the hollow part of the hair and causes what is called a reactioncharisma, is the emission of light. This happens every time the beam of light comes in contact with one side of the hair.

polar bear luminescenceWhen sunlight hits a polar bear’s fur, it triggers a reaction called luminescence

This luminescence is accelerated by light-scattering particles. If you take a close look at the polar bear’s protective fur through a microscope, you can see small bumps – these are light scattering particles. As light bounces around in the hollow shelter, it hits these particles and interrupts the beam of light, causing it to break up into more beams that are emitted in different directions. The rays keep bouncing around, creating more luminescence, until they reach another light-scattering particle, and the process repeats. All of this reflected light in the protective coat causes the fur to glow white, making the polar bear appear white and blending in with its arctic snowice environment!

Light-scattering particles are not only on the inside of the hair, but also on the outside. Polar bears ingest salt particles when swimming or near the ocean’s salt water. These salt particles, along with the rough surface of the hair, also act as light-scattering particles, causing more rays of light to bounce around and create more luminescence.

UV light

Visible Spectrum with UV lightUltraviolet light is found after violet light in the visible spectrum. Image source: Jirka

Light travels in waves, which scientists call wavelengths. The human eye can only see certain wavelengths of light, such as red, orange, yellow, green, blue, indigo, and violet (which make up the ROY G. BIV acronym). Each color has a wavelength that is slightly shorter than the wavelength that precedes it. This light is part of the visible spectrum, but there are other forms of light that we cannot see. Light plays an important role in helping us understand polar bear fur after purple. It’s called ultraviolet light, something you may know as UV light. UV light has a wavelength that is too shortto see humans and other mammals, but it still occurs in sunlight, which is one of the reasons for sunburn and why high UV protection in sunscreen is so important.

When the sun hits a polar bear, the UV rays from the sunlight reach the base of the guard’s fur, where they come into contact with the bear’s dark skin. When UV light hits the skin, it produces a white color due to fluorescence.

protein keratin

Planet earth is rich in keratin. This is the most common protein in the world and is found in skin, nails and hair. Like you, polar bears have horny substance in their hair. These protein molecules are whitish in color, which further contributes to the white color of polar bears’ fur.

What color is the polar bear?

 
Polar bears are white, but their fur is mostly clear! In short…when light hits a polar bear’s almost-obvious protective fur, some of the light is trapped in the fur and reflected around, creating luminescence. When it hits a light-scattering particle on the inside or a salt on the outside, more light is refracted and spread out in all directions. This scattering of light creates more white light due to luminescence. UV rays are also transmitted to the bear’s dark skin along the protective hairs, which causes blooming, not forgetting the protein keratin, whose molecules give it a light white color. Each of these items will bring you the white polar bear you know and love.

Now we know whypolar bearslook white, you’re probably wondering why some polar bears look yellow or brown. Interestingly, with changes in their habitat, their coat aging over the years and season, coat color can show slight differences, helping them adapt to the environment. In late fall and winter, when polar bears shed their old fur and grow new ones, they tend to be whiter a few months later in the summer, when their fur can take on a yellowish tint from wear and tear. . Those that live on ice outside of open water appear whiter than bears that spend a lot of time swimming. On the other hand, polar bears that live on land where there is little or no snow have light brown fur.

Following is a transcript of the video:

Polar bears aren’t actually white.Turns out, they can come in all sorts of colors: yellow, gray, orange, and even green. That’s because polar bear fur is transparent and hollow.When light strikes the outer fur some of it is absorbed while the rest is scattered away.

The result? The fur can appear as different colors under different lighting. Normally, polar bears look white. That’s because their fur is scattering sunlight, which is also white. But on a cloudy day, the bears can look slightly gray. At sunset, they can appear reddish-orange. But lighting is only half the story.

Polar bears in zoos have been known to turn green. Concrete floors in their pens scrape against the fur. The abrasions form tiny holes in their hairs, opening a gateway for algae that can live and breed inside. In the Arctic, temperatures are too cold for these algae. But wild polar bear fur can still change color to yellow, thanks to oils from their prey that stain the fur.

Perhaps the most surprising thing about polar bears? Underneath all that hair, polar bear skin is actually black. The black skin readily absorbs sunlight to keep the bear warm. Polar bears aren’t just the ambassadors of the North Pole. They’re masters at manipulating color to survive.

If you ask any child what color is the polar bear fur, the answer will probably be white. But scientists after years of research have found that polar bears actually have black skin and their fur is transparent (each separate hair is hollow and colorless) and the color of fur seems white because of the way the hair of these animals reflects light.
