A human hair is between 40 and 50 micrometers (microns) wide -- 40 - 50 x 10^-5 meters = 0.000 04 - 0.000 05 meters wide.

Wavelengths of light average between 400 nanometers (violet) to 700 nanometers (red) -- 400 - 700 x 10^-9 meters = 0.000 000 4 - 0.000 000 7 meters length.

The average diameter of an atom is 0.1 to 0.5 nanometers -- 0.1 - 0.5 x 10^-9 = 0.000 000 000 1 - 0.000 000 000 5 meters. (100,000 times smaller than a human hair)

The nucleus of an atom is tens and up to a hundred thousand times smaller than the atom -- 10^-14 = 0.000 000 000 000 05 meters. (50,000 times smaller than the atom)

Planck Length: 10^-35 meters 0.000 000 000 000 000 000 000 000 000 000 000 01 meters.
