Visible Light facts

While investigating facts about Visible Light Spectrum and Visible Light Wavelength, I found out little known, but curios details like:

Scientists detected an atomic nucleus traveling at 99.9999999999999% of the speed of light, with energy 20 quintillion times that of visible light. It was appropriately named the "Oh-My-God Particle."

how visible light is used with solar photovoltaic panels?

Pink lights -- which make skin blemishes more visible --have been installed in public places to deter teenage loitering

What visible light spectrum ranges between?

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 visible light color has the longest wavelength. Here are 50 of the best facts about Visible Light Frequency and Visible Light Spectrum Wavelengths I managed to collect.

what visible light has the highest frequency?

  1. Purple as a color is similar to violet, but violet is a spectral color with its own wavelength on the visible spectrum of light whereas purple is a composite color, made by combining red and blue.

  2. In 1948, A man was found dead on a beach in Adelaide and the words "Taman Shud", torn from a book, in a hidden pocket. The rest of the book was found in a nearby car, with a mysterious code on a page only visible under UV Light. The code and the identity of the man has never been solved

  3. One-third of humanity (including 60% of Europeans and 80% of North Americans) live in such light polluted areas that the Milky Way is not visible at night.

  4. The first ever synthetically produced color pigment, Egyptian blue, was created around 2,200 B.C. In 2006 scientists discovered it glows under fluorescent lights, allowing us to detect it on artifacts where it is no longer visible to the naked eye.

  5. In 1054, Chinese astronomers noted a bright "guest star" in Taurus that was visible in the daytime for 3 weeks, and didn't completely fade out for almost two years. The "guest star" was actually the supernova explosion that created the Crab Nebula, which is located some 6,500 light-years away.

  6. Although violet and purple look very similar, violet is a true color with its own set of wavelengths on the spectrum of visible light, while purple is a composite color made by combining blue and red

  7. The Sun's emits more green visible light than any other color but we still see the color mixture as white. It only appears yellow because shorter wavelength colors such as blue scatter in the atmosphere, making the sky blue.

  8. The reason why medicine bottles are orange or light brown is because of its ability to prevent ultraviolet light from degrading the contents through photochemical reactions, while still letting enough visible light through the bottle for the contents to be seen.

  9. Prescription bottles are typically orange or light brown because those colors prevent ultraviolet light from degrading the potentially photosensitive contents through photochemical reactions, while still letting enough visible light through for the contents to be easily visible

  10. The color magenta does not have a wavelength. It's the product of combining red and blue light, which are on the opposite ends of the visible light spectrum, so our brains fill in the gap with what they think the color should be.

Why visible light communication?

You can easily fact check why visible light spectrum by examining the linked well-known sources.

The star Betelgeuse, in the constellation Orion, is 500 times bigger and emits 16,000 times more visible light than the Sun. If it were in our solar system, its surface would extend to the orbit of Jupiter.

West and East Berlin used two different kinds of street lights during the Cold War, producing different colours that are still visible from space, almost 30 years after the wall fell. - source

Chameleon bones are fluorescent in UV light, and can even be seen through their thin skin. The more visible glowing patterns of tubercles (bony projections) can help identify a chameleon's species and gender.

Magenta does not exist in the visible light spectrum and does not have a corresponding wavelength, so your brain interprets it as "not green" - source

When are the northern lights visible?

West and East Berlin used different streetlights during the Cold War, with the East using sodium vapour lights that produce yellower colour and the West using fluorescent lights with whiter colours. Years after the Berlin Wall fell the different colours are still visible even from space.

How visible light spectrum?

In 1880 Alex Graham Bell, inventor of the telephone, also invented the photophone, a device that transmits sound using visible light. Although he called it his greatest invention, it wasn't until the 1980s, over a century later, that it precursed fibre optics, the backbone of the modern Internet

there are brown dwarf stars which emit little to no visible light and can be as cold as - 55° to 8° F. They can be between 13 and 80 times the mass of Jupiter and fuse Lithium instead of Hydrogen.

Mantis Shrimp have one of the world's best eyes. They have up to 16 photoreceptors and can see UV, visible and polarised light.

The meteor that hit the Russian town of Chelyabinsk, The light from the meteor was brighter than the Sun, visible up to 100 km (62 mi) away and released 26 to 33 times as much energy as that released from the atomic bomb detonated at Hiroshima.

The world's most advanced visible-light astronomical observatory is named the VLT, for Very Large Telescope

When are the northern lights visible in alaska?

Red light does not reach ocean depths, so deep-sea animals that are red actually appear black and thus are less visible to predators and prey

Males have orange-brown head, grey-brown back, black breast and white belly during the breeding season. They also have thick collars (ruffs) on the neck and tufts of long, bright feathers on the head that can be spread out. Outside the breeding season, males and females are grey-brown colored and have light-colored plumage on the belly. White, U-shaped marking on the bottom side of the tail is clearly visible during the flight.

Blue light scatters the most in the atmosphere and is therefore least visible by aircrafts at night. 1939 German engineers knew that and installed blue lights on their emergency vehicles, to be spotted less easily by bombers. This is the origin of the blue emergency light.

Aluminium reflects about 92% of visible light.

Certain algae (called Dino-flagellate) produce light (phenomenon called bioluminescence) that is easily visible during the night. Large groups of algae produce enough light to ensure reading of the newspapers without any additional source of light.

How visible lights?

Calcite is also phosphorescent in that after being disconnected from a non-visible UV light, it still glows.

Tuatara has third eye (called parietal eye) that is visible on top of the head of hatchlings. After 4 to 6 months, this structure becomes covered with scales. Third eye contains elements of regular eye such as retina, cornea and nerve endings. Tuatara probably uses it to detect daily changes in light and seasonal changes.

Detergent "Makes whites whiter!" by using an additive that absorbs UV light and emits it back as visible light that makes the clothes look brighter, and whiter.

Scorpions glow under black light. Certain molecules in a part of a scorpion's exoskeleton absorb the UV light and emit it as wavelengths of visible light that appear blue-green at night.

The mesh in a microwave oven door lets you see through it while shielding you from microwaves because the size of the perforations is a lot smaller than the microwaves' wavelength. The visible light however, can still pass through the holes and lets you see the inside of the oven.

Of all the forms of radiation and light on the electromagnetic spectrum, humans can only visibly see a very small amount of light.

Greta oto is called a glass-winged butterfly as it has unique fully transparent wings that allow it to camouflage easily, due to wing material having low absorption of visible light.

Light is also called electromagnetic radiation when speaking of light other than visible light.

The color of the average mirror isnt white light or whatever its reflecting, it's green. Most modern, mass produced mirrors are made of a soda-lime silica glass with a silver backing. This combination of materials reflects more green light than other visible wavelengths.

Bleaching" a stain only conceals its appearance by altering its chemical structure and its associated wavelength of absorption/reflection, but would still be visible under UV light.

The study of the Sombrero in visible and infrared light has been studied using the Hubble Space Telescope and the Spitzer Space Telescope.

Some birds have patterns in their feathers that are invisible to humans, but which become visible under ultraviolet light. Since birds have UV vision, the patterns are likely used for mating displays.

Isaac Newton built the first practical reflecting telescope and developed a sophisticated theory of colour based on the observation that a prism decomposes white light into the colours of the visible spectrum.

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

The green flash, an optical phenomenon that occurs during sunset or sunrise. The color green is occasionally visible for a few seconds, and happenes because Earth's atmosphere can separate the light into the spectrum.

This is our collection of basic interesting facts about Visible 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 Visible Light so important!
