White light

About white light
  • White light is the term for light that contains all wavelengths of the visible spectrum at the same intensity.
  • The term ‘white light’ doesn’t imply that light appears white while travelling through the air. As light travels through the air it is invisible to our eyes.
  • When white light hits a neutral-coloured surface, object or medium, and all wavelengths are reflected, it appears white to the observer.
