![]() Extending just beyond the visible region in the other direction from 700 nm and higher is the infrared region of light radiation. Therefore, it is possible to produce images that may only be observed using photography. Although we cannot see this light, it is reactive with photographic materials. Below violet from 200 to 400 nm is the ultraviolet region. The areas extending in either direction beyond the visible spectrum are the invisible regions of light. The visible region of the light spectrum ranges form 400 to 700 nanometers (nm) in wavelength. These wavelengths increase in the direction from blue to red along the length of the spectrum.
