# Do photons have a spectrum like light when they are treated as waves?

If light can be treated as both a particle and a wave, are there things called infrared photons, or ultraviolet photons etc, as there are infrared waves, or ultraviolet waves? Or are photons just packets of energy, as in they have specific quantities of energy that correspond to the different wavelengths of light when taken as a wave. Or is it just that the spectrum only exists if light waves are dispersed, but photons don't get dispersed? The recent photograph of light also doesn't seem to explain this either..or at least I don't see it.

• I forgot the word "light", thanks. – tkhanna42 Mar 6 '15 at 9:55
• What photograph? – Oebele Mar 6 '15 at 11:00

How this works is the following. A "lone photon" is simply a state of the quantum electromagnetic field, see the "Quantization of the Electromagnetic Field" Wikipedia article where the number observable is certain to return a measurement of $n=1$.
