What is the visible spectrum or visible light waves?


The visible spectrum is basically the portion of the electromagnetic spectrum that our eyes can see – visible light. Remember, not all light forms are visible to human eye.


We see these light waves as the colours of the rainbow. Each colour has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light.
