A visual representation of the visible light spectrum
A VISUAL REPRESENTATION OF THE

Visible Light Spectrum

The electromagnetic radiation in the range of the visible spectrum(the electromagnetic spectrum that is visible to the human eye) is what we know as LIGHT.

When refracted through a prism, light is divided into a spectrum of colors - resulting 7 spectrum colors or, the rainbow!

100nm Ultraviolet wavelength 380nm

Violet

380-450Nm
668-789THz
2.75–3.26eV

With the shortest wavelength(380-450Nm) of all the visible colors, Violet is at the end of the spectrum of visible light, between blue and the invisible ultraviolet.

Fun Facts

380nm wavelength 450nm

Blue

450–485Nm
620–680THz
2.64–2.75eV

Blue is the colour of light between violet and green on the visible spectrum. Human eyes perceive blue when observing light which has a dominant wavelength of roughly 450–485 nanometres.

In painting and traditional colour theory, blue is one of the three primary colours of pigments (red, yellow, blue), which can be mixed to form a wide gamut of colours.

Fun Facts

450nm wavelength 485nm

Cyan

485–500Nm
600–620THz
2.48–2.52eV

Cyan sits right between the wavelengths of green and blue.

In the CMYK color system, cyan is one of the primary colors, along with magenta, yellow, and black.

Fun Facts

485nm wavelength 500nm

Green

500–565Nm
530–600THz
2.25–2.34eV

Green is the color between blue and yellow on the visible spectrum.

By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy.

Fun Facts

500nm wavelength 565nm

Yellow

565–590Nm
510–530THz
2.10–2.17eV

Sitting between orange and green on the spectrum of visible light, Yellow is a primary color in subtractive(CMYK) color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity.

Traditionally, the complementary color of yellow is purple.

Fun Facts

565nm wavelength 590nm

Orange

590–625Nm
480–510THz
2.00–2.10eV

Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 590 and 625nm.

The orange colour of carrots, pumpkins, sweet potatoes, oranges, and many other fruits and vegetables comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the sun into chemical energy for the plants' growth.

Fun Facts

590nm wavelength 625nm

Red

625–740Nm
405–480THz
1.65–2.00eV

Red is the color at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan.

In the language of optics, red is the color evoked by light that stimulates neither the S or the M (short and medium wavelength) cone cells of the retina, combined with a fading stimulation of the L (long-wavelength) cone cells.

Fun Facts

625nm wavelength 740nm

Infrared Radiation(IR)

740-1000Nm
480THz - 300Ghz
1.7eV – 1.24meV

Infrared radiation (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with longer wavelengths than those of visible light, and is therefore generally invisible to the human eye.

In the language of optics, red is the color evoked by light that stimulates neither the S or the M (short and medium wavelength) cone cells of the retina, combined with a fading stimulation of the L (long-wavelength) cone cells.

Fun Facts

740nm wavelength 1000nm
