To help compare different orders of magnitude this page lists lengths between 10^-7 and 10^-6 m (100 nm and 1 µm).

• Distances shorter than 100 nm
• 100 nm — greatest particle size that can fit through a surgical mask
• 120 nm — greatest particle size that can fit through a ULPA filter [1]
• 125 nm — standard depth of pits on compact discs (width: 500 nm, length: 850 nm to 3.5 µm)
• 180 nm — typical length of the rabies virus
• 200 nm — typical size of a Mycoplasma bacterium, among the smallest bacteria
• 280 nm — near ultraviolet wavelength
• 300 nm — greatest particle size that can fit through a HEPA filter
• 380-420 nm — wavelength of violet light (see color and optical spectrum)
• 420-440 nm — wavelength of indigo light
• 440-500 nm — wavelength of blue light
• 500-520 nm — wavelength of cyan light
• 520-565 nm — wavelength of green light
• 565-590 nm — wavelength of yellow light
• 590-625 nm — wavelength of orange light
• 625-740 nm — wavelength of red light
• Distances longer than 1 µm
