Infrared light, microwaves and radio waves have wavelengths longer than visible light. Radio waves have the longest wavelength.
  Red is the longest visible wavelength, and violet is the shortest.   There are other wavelengths of 'light' that are longer than red or   shorter than violet, but they're not 'visible' just because the  stuff in the   back of your eye doesn't respond to them even when they shine on  it.   The shortest visible wavelength is around 400 nano (billionth of a)  meters.
