Cyan: 500 – 550 nm; Green: 550 – 580 nm; Yellow: 580 – 600 nm; Orange: 600 – 650 nm; Red: 650 – 700 nm; Violet: 400 – 450 nm. Violet light has a wavelength between 400 and 450 nm. The human eye tends to mistake violet and purple easily. However, the colors are quite distinct. Purple is a mix of red and either blue or violet.
White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. Light from a torch or the Sun is a good example of this. Light from a laser is monochromatic, which means it only produces one colour. (Lasers are extremely dangerous and can cause permanent eye damage.
Jun 7, 2024 · The wavelengths of visible light are: Violet: 380–450 nm (688–789 THz frequency) Blue: 450–495 nm. Green: 495–570 nm. Yellow: 570–590 nm. Orange: 590–620 nm. Red: 620–750 nm (400–484 THz frequency) Violet light has the shortest wavelength, which means it has the highest frequency and energy. Red has the longest wavelength, the ...

Jan 16, 2021 · The visible light spectrum is the region of the electromagnetic spectrum that human eyes see. It runs from wavelength of about 400 nanometers (nm) at the violet end of the spectrum to around 700 nm at the red end of the spectrum. Ultraviolet light and x-rays are the ionizing radiation beyond violet, while wavelength on the other side of red are ...
Blue. 492 - 455. Violet. 455 - 390. 1 Angstrom = 10 -10 meters. The order of colors in light, arranged from shortest wavelength to longest, is called the visible spectrum of light. The image below shows light's visible spectrum, which runs from violet to red. You might recognize the spectrum as the order of colors in a rainbow.

On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow. Combining primary colors of light like red, blue, and green creates secondary colors: yellow, cyan, and magenta.

Oct 21, 2024 · If more red light is added or if the intensity of the green light is decreased, the light mixture becomes orange. Similarly, if there is more green light than red light, a yellow-green is produced. The RGB colour model , one of the three main colour models, is an additive model used in digital devices and light-based media to create a gamut of colours from just red, green, and blue.
