A nm is .0000000001 of a meter. It is used as a measure of
wavelength. 1nm is somewhere in xrays in the electromagnetic
spectrum,
which would be above visible light. Some measure frequency
instead using hertz(cycles/sec).
1000nm or also known as 1 micrometer would of course, put you
below visible light in the intermedate infrared part of the
spectrum.
