can reindeer see ultraviolet light?

Lead researcher Professor Glen Jeffery said "We discovered that reindeer can not only see ultraviolet light but they can also make sense of the image to find food and stay safe. ... In the process of blocking UV light from reaching the retina, our cornea and lens absorb its damaging energy and can be temporarily burned.

ultraviolet light is below violet light and invisible to the human eye. infrared light is above red on the spectrum and also invisible. ... These colors range from a deep violet to red and comprise the visible light spectrum. ultraviolet light is below violet light and invisible to the human eye.

In fact, most Arctic animals do not change color with the seasons at all, even species closely related to those that do. One theory is that a pale coat may have better insulating properties—because melanin, the substance responsible for colored hair, is absent from white fur, leaving air spaces in the hair shaft.

Ultraviolet and infrared radiation are both electromagnetic radiation. Ultraviolet has a shorter wavelength (and the photons are more energetic) than visible light. Infrared has a longer wavelength and less energetic photons.

Ultraviolet radiation lies between visible light and X-rays along the electromagnetic spectrum. UV "light" spans a range of wavelengths between about 10 and 400 nanometers.

Black light is a kind of UV light. Black lights emit ultraviolet radiation (UV light). UV is radiation with a wavelength just shorter than that of violet light, which is the shortest wavelength of light in the visible part of the electromagnetic spectrum.

The large size of the retina also allows for rather good night vision, and a filament like Tapetum Lucidium, similar to the kind found in cows contributes greatly to night vision. Interestingly Sheep and Goats are farsighted with a slight astigmatism, another common trait of prey animals.

Ultraviolet (UV) light has shorter wavelengths than visible light. Though these waves are invisible to the human eye, some insects, like bumblebees, can see them! ... Our Sun emits light at all the different wavelengths in electromagnetic spectrum, but it is ultraviolet waves that are responsible for causing our sunburns.

Deer, antelope, elk, sheep, goats and pigs only have the bluish light cells and the green-yellow light cells. They can only see in these colors. Purple, red, pink, and orange don't make an appearance. This is why orange has become the safety color for hunters in the field.

Fluorescence only happens while UV radiation is present. Normal incandescent light bulbs (those that use hot filaments to produce light) do not emit UV radiation, and the fish would appear comparatively dull in colour. ... (In fact, the word 'fluorescence' comes from fluorite – a substance that glows blue in UV light.)

Ultraviolet telescopes allow astronomers to study things such as the composition of the gas that exists between stars. Electromagnetic radiation with wavelengths between those of radio waves and visible light is called infrared light.

Most snakes examined in the study are sensitive to UV light, which allows them to see well in low light conditions. ... These species have probably also tuned the pigments in their retina so that they are no longer sensitive to the short-wavelength UV light.

But not all types of UV are the same. ... While UV is commonly called, "UV light," the spectrum technically falls just outside of the visible light spectrum.

Deer eyes lack the ultraviolet light filter that human and other longer-lived animals have, which means they see blues and other short-wavelength colors about twenty times better than we do. “Blue jeans are much more vivid to a deer than blaze orange,” said Murphy.

Some insects, like bees, can see light of shorter wavelengths than humans can see. What kind of radiation do you think a bee sees? Bees see ultraviolet radiation.

Insects, and especially moths, are particularly sensitive to the UV part of the electromagnetic spectrum. ... A common theory is that moths are attracted to the moon, and therefore they should fly higher on moonlit nights.
