NanoWave. Oldschool phsysics term. NanoMeter snuck it's way in as a measure of unit called the Millimicron (mµ), as a way to measure a lightwave form. Since all light is a wave form and nano is a form of measure then a nanowave is the measure of a specific range of light. A really really really tiny-itsy-bitsy wave in the spectrum.
EDIT: But essentially is the same thing referred to as NM, just without the explanation. When your talking about light it is a given what you are talking about but NM can be used for measuring anything.
