White light is the name given to visible light that contains all wavelengths of the visible spectrum at equal intensities. As light travels through a vacuum or a medium it is described as white light if it contains all the wavelengths of visible light. As light travels through the air it is invisible to our eyes.

May 2, 2024 · 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.
White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. Light from a torch or the Sun is a good example of this.
