Pretty much the same thing it means in any distance measurement: nanometers (a billionth of a meter).
nm stands for nanometre, a nanometre is one billionth of a metre, 1 x 10-9 metre.
Nanometers.
wavelength of chloride is 450 nm
The wavelength is 610 nm.
406 nm
488 nm
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant object. We say that the object's spectrum is red shifted.
670.8 nm is the wavelength.
about 435 nm
1 nm - 750 nm
wavelength of chloride is 450 nm
nm = nanometers It is a measure of the wavelength of the light, with energy inversely proportional to the wavelength: E = h / wavelength
X rays have a wavelength of 4.2 nm.
The wavelength is 610 nm.
406 nm
67676777671 nm- 750 nm
A ruby laser is a red laser with a wavelength between 694 nm and 628 nm. 1 nanometer = 1×10−9 meter.
The wavelength is 436 nm.
