What is the smallest thing you can see?

The smallest thing that we can see with a ‘light’ microscope is about 500 nanometers. A nanometer is one-billionth (that’s 1,000,000,000th) of a meter. So the smallest thing that you can see with a light microscope is about 200 times smaller than the width of a hair. Bacteria are about 1000 nanometers in size.
