If you mean nanometer, that's abbreviated "nm" (lowercase), and the answer is a million.
One million nanometer.
1 daNm = 10 Nm
According to Wikipedia (see link), a human eye with excellent acuity can distinguish between lines that are 0.35 mm apart, held at a distance of 1 meter. That is 350 micrometres or 350,000 nm - somewhat larger than the 250 nm in the question!
there are many units which are smaller than a cm . The metric unit smaller than a cm is mm. all other units are µm,pm ,nm ,fm ,etc.
The wavelength of 16 nm is 16 nanometers, which falls within the ultraviolet region of the electromagnetic spectrum. In this range, the light has shorter wavelengths than visible light but longer than X-rays.

0.000001 mm is 1 nm. This is because the nanometer is much smaller than the mm. there are 1 million nm in a mm.
One million nanometer.
0.05 nm
The wavelength of ultraviolet waves is shorter than the wavelength of infrared waves. Ultraviolet waves have wavelengths ranging from 10 nm to 400 nm, while infrared waves have wavelengths ranging from 700 nm to 1 mm.
What is a nanometer? 10 to the -9 meters. Also known as a very small part of a meter. Now which is longer- 20 meters, or 250 meters? 250 of course! And if you divide them both by 10 to the 9th, it'll still hold true. 5 is greater than 3, and 5/4 is still greater than 3/4.
Humans can see light with wavelengths ranging from about 400 to 700 nanometers. This corresponds to the colors of the visible spectrum: violet, blue, green, yellow, orange, and red. Wavelengths shorter than 400 nm (ultraviolet) and longer than 700 nm (infrared) are invisible to the human eye.
Yes, NM is shorter than MM. NM stands for nanometer and is equal to one billionth of a meter, while MM stands for millimeter and is equal to one thousandth of a meter. Therefore, NM is smaller than MM.
Between 1 nanometre and 1 micrometre (= 1000 nm).
Human vision is limited to the visible spectrum of light, which ranges from about 400 to 700 nanometers. Wavelengths shorter than 400 nm (such as ultraviolet light) and longer than 700 nm (such as infrared light) are not visible to the human eye.
Infra-red radiation has a wavelength adjacent to but longer than visible light.
