The wavelength range where optical radiation is visible does not have sharp borders. Here, the wavelength band of 380 nm to 780 nm is used. There is an overlap with the UV wavelength range that extends to 400 nm and in the upper range with Infrared.

1 de abr. de 2020 · 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.
Photopic (black) and scotopic (green) luminous efficiency functions. The horizontal axis is wavelength in nm. See luminous efficiency function for more info. The visible spectrum is limited to wavelengths that can both reach the retina and trigger visual phototransduction (excite a visual opsin ).
Wavelength (nm) Red: 780 - 622: Red: 780 - 622: Orange: 622 - 597: Yellow: 597 - 577: Green: 577 - 492: Blue: 492 - 455: Violet: 455 - 390
Wavelength Frequency IR-A: 780 – 1,400 nm (0.78 – 1.4 μm) 215 – 430 THz IR-B: 1,400 – 3,000 nm (1.4 – 3 μm) 100 – 215 THz IR-C: 3,000 – 1 mm (3 – 1,000 μm) 300 – 100 THz
Electromagnetic radiation with a wavelength between 380 nm and 760 nm (400–790 terahertz) is detected by the human eye and perceived as visible light. Other wavelengths, especially near infrared (longer than 760 nm) and ultraviolet (shorter than 380 nm) are also sometimes referred to as light, especially when the visibility to ...
