Light Wavelengths facts

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

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.

how many wavelengths of light are represented in the diagram below?

There’s a Japan indoor vegetable-factory that produces 10,000 heads of lettuce a day while using just 1% of the amount of water needed for outdoor fields. LEDs emit light at ideal wavelengths for plant growth, while also optimizing night and day cycles, allowing lettuce to grow 2.5 times faster.

What light wavelengths are most effective for photosynthesis?

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 wavelengths of light does chlorophyll a absorb best. Here are 50 of the best facts about Light Wavelengths For Plant Growth and Light Wavelengths And Photosynthesis I managed to collect.

what light wavelengths are best for plant growth?

Gold is yellow, unlike its grey neighbors on the periodic table, due to Einstein's special relativity: the electrons are moving so fast, some over half the speed of light, that they have relativistic contraction, shifting the wavelength of light absorbed to blue and thus reflecting a golden glow
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
If human were sensitive to light of all wavelengths, Betelgeuse would be the brightest star in the sky (other than the Sun).
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.
Scientists have developed a Laser of a very specific wavelength that is able to refrigerate by causing the object hit to release a photon which carries away more energy in the form of light than it absorbs.
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.
In 2014 Japan debuted the world's largest indoor farm using LED lights that emit wavelengths optimal for plant growth; The upshot: grows 2.5x faster than outdoors; reduces produce loss from 50% to just 10% and cuts water usage to just 1%
The real color of the sun is white. It just appears yellow to us due to earths atmosphere scattering the higher wavelengths of light.
Magenta does not exist in the visible light spectrum and does not have a corresponding wavelength, so your brain interprets it as "not green"
When he applied spectral analysis to the study of the Sun, he discovered that when light is passed through a gas, the gas absorbs those wavelengths it would have emitted if heated.

light wavelengths facts — What wavelengths of light are used in photosynthesis?

Why do different wavelengths of light refract differently?

You can easily fact check why are only certain wavelengths of light emitted by atoms by examining the linked well-known sources.

Since red wavelengths of light are absorbed the first 10-20 feet of water, blood looks green below 50 feet

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. - source

The reason we see different colors of light is because each color has a different wavelength.

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.

Some plants, notably certain Begonia and Selaginella sp. developed a very specific arrangement of chloroplasts called "iridoplasts" that helps catch wavelengths of light in low light conditions. The leaves of these plants form beautifully metallic blue iridescent shimmers like a peacock. - source

When observed from earth the wavelengths of light emitted?

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.

How many wavelengths of light are there?

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 colors in a butterfly's wings are actually generated not from pigments but by the size of the scales in them making them absorbing light of certain wavelengths

Blue feathers do not actually exist; while many birds may appear blue, this is not caused by chemical pigments, but because of an optical illusion created by microscopic prismatic structures on the surface of the feather reflecting only certain wavelengths of light

A Cancer fighting technique exists called Photodynamic therapy.You ingest a chemical that collects in cancer cells and reacts after being manually exposed to a source of light of a particular wavelength, creating a form of oxygen which kills cells near by.

IPhone’s night mode is warmer to emit a different wavelength of light and not inhibit your body’s melatonin production, not just because it’s easier on the eyes.

Are all wavelengths of light equal when it comes to phototropism?

In the 19th century Scottish physicist James Clerk Maxwell was the first to propose using a wavelength of light as the basis for measuring length, as is now standard. At the time, length was defined using the body or the Earth. He died decades before the technology to measure light was invented.

The Stoplight Loosejaw belongs to a genus of fish that produce red bioluminescence, and as most of their prey organisms are not capable of perceiving light at those wavelengths, this allows them to hunt with an essentially invisible beam of light.

Fluorescence of visible wavelengths under ultraviolet (UV) light has been previously detected in a wide range of birds, reptiles, and amphibians and a few marsupial mammals. It was recently discovered in New World flying squirrels, they glow a brilliant, bubble-gum pink under ultraviolet light.

The wavelengths of light that are reflected off an object (it's "colour") is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to quantum laws.

The process of photosynthesis is affected by many factors including light intensity, light wavelength, the level of available carbon dioxide, and the temperature.

How different wavelengths of light affect photosynthesis?

Redshift is the stretching of wavelengths due to the expansion of the universe, it is called redshift because red on the visible light spectrum has longer wave lengths then others colors so over time as the universe expands the colors will change from a smaller to a larger wavelength.

Blood deprived oxygen is not blue. Veins look blue because light has to penetrate the skin to illuminate them, blue and red light (being of different wavelengths) penetrate with different degrees of success

How chameleons change colors. Using nanocrystal-containing cells in their skin, called iridophores, chameleons can reflect different wavelengths of light by moving the crystals closer together for shorter wavelengths of light (blue) or farther apart to reflect longer wavelengths of light (red).

Sodium-vapor lamps emit light at two close wavelengths 589nm/589.6nm absorbing all other colours making things look like they’re in a black and white movie illuminated by an orange light including fire which looks black when it reacts with salt water and will even cause it to cast a shadow.

Microwave ovens have the same frequency and wavelength of light as a wifi router, so a microwave is like "bright" wifi signal cooking your food!

Water selectively scatters and absorbs certain wavelengths of visible light. It is the blue wavelength that penetrates the deepest, which is why deep, clear ocean water and some tropical water appear to be blue most of the time.

Bobtail squids have a symbiotic relationship with bioluminescent bacteria, which inhabit a special light organ in the squid's mantle. The organ contains filters which may alter the wavelength of luminescence closer to that of downwelling moonlight and starlight.

The word laser is actually an acronym which stands for light amplification by stimulated emission of radiation, where the photons which compose the laser are coherent, meaning the photons all have the same wavelength, opposed to visible light which has several wavelengths composing any ray.

Brown noise, unlike white, pink and grey noise, is not named after a color. Instead, it is named after Scottish botanist Robert Brown. TIalsoL that white noise is named after white light, because it is has equal levels on all wavelengths of the audio spectrum.

The main reason eyes see in the "visible" spectrum" is because the earliest species to develop photosensitivity were aquatic, and only two specific wavelength ranges of electromagnetic radiation, blue and green visible light, can travel through water.

Tattoo removal lasers use specific wavelengths of light to target specific ink colors

Blue wavelengths are the most potent portion of the visible electromagnetic spectrum for circadian regulation, and therefore avoiding blue light in the hours before bedtime helps improve sleep quality.

There is a significant difference between violet and purple. Violet is a true color, with its own wavelength on the spectrum of visible light, while purple is a created composite color, made by combining blue light at high intensity with low intensity red light.
