Detailed explanation-1: -Currently, the smallest thing that can be seen using a microscope is about the size of an atom.
Detailed explanation-2: -Electron microscopy is widely used in virology because viruses are generally too small for a direct inspection by light microscopy. Analysis of virus morphology is necessary in many circumstances, e.g., for the diagnosis of a virus in particular clinical situations or the analysis of virus entry and assembly.
Detailed explanation-3: -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.
Detailed explanation-4: -The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across.
