What does 1 nm look like?
One nanometer is about as long as your fingernail grows in one second.
The smallest thing you can see with your naked eye is about 40-50 microns, or about the width of a human hair. So now, 1000 times smaller than that is nanometer. We can't see it with the human eye, unless we have a very powerful microscope. Remember, a nanometer is a billion times smaller than a meter (you!).
One nanometre can be expressed in scientific notation as 1×10−9 m, and as 11000000000 metres.
A nanometer is one billionth of a meter, 0.000000001 or 10-9 meters. The word nano comes from the Greek word for “dwarf.” The term nanoscale is used to refer to objects with dimensions on the order of 1-100 nanometers (nm).
To give you some idea of the nanoscale, 10 hydrogen atoms laid side by side measure a nanometre across, a strand of DNA is 2.5 nm in diameter, while a red blood cell is about 7000 nm wide.
Human cells, such as red blood cells, are about 10,000 nanometers across.
Experts believe that the naked eye — a normal eye with regular vision and unaided by any other tools — can see objects as small as about 0.1 millimeters.
no, a nanometer is much smaller than the wavelength of light, so you can not even see it with an optical microscope. Show activity on this post. Think about it. Visible light has wavelengths roughly from 400 to 700 nm.
Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
A nanometer (nm) is equal to one-billionth of a meter.
The prefix "nano" literally means one-billionth. Written out, one nanometer looks like 0.000000001 m (that's nine zeros!).

Atoms are smaller than a nanometer. One atom measures ~0.1-0.3 nm, depending on the element.
A strand of hair is about 80,000 to 100,000 nanometers wide. A sheet of paper is 100,000 nanometers thick. An ant is 5 million nanometers long. The human hand is 100 million nanometers long.
In the International System of Units, the prefix "nano" means one-billionth, or 10-9; therefore, one nanometer is one-billionth of a meter. It's difficult to imagine just how small that is, so here are some examples: A sheet of paper is about 100,000 nanometers thick.

(1) The very simple part: after nanometer is picometer. Just like nanometer was preceded by micrometer. It's just standard SI prefixes.
