What is the wavelength range of visible light?

Answer 1

400 (violet) to 700 (dark red) nanometers is the standard range stated in most sources.

Answer 2

Overall, the range of visible light is 380-750 nm

For each color:

violet 380-450 nm

blue 450-495 nm

green 495-570 nm

yellow 570-590 nm

orange 590-620 nm

red 620-750 nm

Answer 3

It actually varies a little bit for different peoples' eyes. The range is in the neighborhood

of 380 to 750 nanometers, with the limits depending on the individual.

That's 0.00000038 meter (at the blue end) to 0.00000075 meter (at the red end).

Answer 4

The range of wavelength of visible light is 380-750nm.
