What are the wavelengths and colors of visible light?

Colors of the Visible Light Spectrum

  • Violet – shortest wavelength, around 400-420 nanometers with highest frequency.
  • Indigo – 420 – 440 nm.
  • Blue – 440 – 490 nm.
  • Green – 490 – 570 nm.
  • Yellow – 570 – 585 nm.
  • Orange – 585 – 620 nm.
  • Red – longest wavelength, at around 620 – 780 nanometers with lowest frequency.

What wavelength does visible light have?

380 to 700 nanometers
What is the visible light spectrum? The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.

What are the wavelengths of different colors?

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)

What are dark colours?

Dark colors are colors with low light intensity. In an RGB color model, the darkness of a color can be approximated by the sum of its red, green and blue values. Dark colors can include a wide range of hues. However, certain colors such as pink, yellow and white are inherently light colors.

Why are there different wavelengths of light?

We see different wavelengths of light as different colors because they are associated to different wavelength, which activates different cells in the retina.

What color is 500nm?

blue 424–491 424–491
violet 400–424 380–424

Which Colour of light has maximum wavelength?

colour Red
The colour Red has the longest wavelength and violet has the shortest wavelength in the visible spectrum.

What color are the longest waves of light?

The spectrum of visible light runs from violet to red. It is banded on either side by ultraviolet and infrared, colors which human beings cannot perceive unassisted. Red light has the longest wavelength with about 650 nm.

Which color of light has the highest wavelength?

Therefore violet has the highest frequency and the shortest wavelength of the visible colors of light. And red has the lowest frequency and the longest wavelength of the visible colors of light. Light travels at 3×10^8 m/s in vacuum.

What colors are associated with wavelength?

Violet: 380–450 nm (688–789 THz frequency)

  • Blue: 450–495 nm
  • Green: 495–570 nm
  • Yellow: 570–590 nm
  • Orange: 590–620 nm
  • What are the wave lengths of the different colors of light?

    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)
