Wavelength range: 622 ~ 760 nm

2. Green light:

Wavelength range: 492 ~ 577 nm

3, blue light:

Wavelength range: 435 ~ 450 nm

Extended data:

Infrared, ultraviolet, x-ray, etc. All are invisible light.

Infrared light has a lower frequency than red light and a longer wavelength than red light.

Ultraviolet and X-rays have higher frequency and shorter wavelength than violet light.

Wavelength range of light wave: 400~760nm (vacuum).

Light wave usually refers to visible light in the electromagnetic spectrum. Visible light usually refers to electromagnetic waves with a frequency range of 3.9×1014 ~ 7.5×10/4 Hz, and its wavelength in vacuum is about 400~760nm.

The propagation speed of light in vacuum is c = 3×10.8m/s, which is the fastest speed of material movement in nature. Light waves are shear waves, in which the electric field intensity E and the magnetic induction intensity B (or the magnetic field intensity H) are perpendicular to each other and to the propagation direction.
