Wavelengths from Red to Violet

TRY SOME QUICK QUESTIONS AND ANSWERS TO GET STARTED
Yes! Visible light is a form of electromagnetic radiation.
There are billion (1,000,000,000) nanometres in a metre.
Infrared and ultraviolet are forms of electromagnetic radiation with wavelengths just outside the visible spectrum.
nm is shorthand for nanometre.

About the diagram

About the diagram
  • This diagram is about which wavelengths of electromagnetic radiation correspond with the different colours we see in the world.
  • The important fact to remember is that the wavelengths of light within the visible spectrum correspond with the spectral colours we see between red and violet.
  • The white arrows in the diagram show the Sun emitting sunlight at all wavelengths of the visible spectrum.
  • The term white light is used when all wavelengths and the colours of the visible spectrum are mixed together.
  • The full spectrum of colours between red and violet illustrates that each and every wavelength between 700 and 430 nanometres produces a different colour.
  • The list on the left shows the ranges of wavelengths that correspond with the most prominent spectral colours
  • The scale along the bottom is marked in nanometres and shows the visible spectrum divided into coloured bands.
Remember that:
  • Objects appear to be different colours to an observer depending on their wavelength.
  • The name given to light that contains all wavelengths of the visible spectrum is white light.
  • When all wavelengths contained in white light reflect off a neutral-coloured surface then the object appears white to an observer.
  • When a narrow band of wavelengths reflect off a neutral-coloured surface then the object appears coloured to an observer.
  • The colour an observer sees depends on:
    • The wavelengths of visible light emitted by a light source.
    • The wavelengths absorbed or reflected off an object.
  • Although a human observer can distinguish between many thousands of wavelengths of light in the visible spectrum, the impression is often of predominant bands of colour.
