White light is dispersed by a glass prism into the colors of the visible spectrum. The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light).
6.1.1 Describe the region of the electromagnetic spectrum that is perceived by our visual system, and the relative energy of photons at long and short wavelengths. 6.1.2 Describe the major parts of the eye and their role in focusing light to create a clear image. In this section, we will meet the range of the electromagnetic energy spectrum ...
The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.
Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10 -7 m, which is red). It is also known as the optical spectrum of light or the spectrum of white light.

10 sie 2016 · 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.
Accurate measurement of wavelengths requires an understanding of the scale and proportion of the light waves being measured. (Example: Students will note, as they collect wavelength measurements, that the unit of measurement for the wavelengths of visible light is the nanometer.)
