Detailed explanation-1: -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.

Detailed explanation-2: -Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it. Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.

Detailed explanation-3: -The wavelength range of the visible spectrum extends from violet (400 nm) to red (750 nm).
